How do you recognize original Koshi chimes?
Mar 05, 2021
Knowing what you are looking at before you buy is straightforward once you know what to look for. The original Koshi chime has several identifying features that imitation versions cannot convincingly replicate: the color-coded laser engraving on the bamboo tube, the quality and density of the bamboo itself, the weight and balance in the hand, the cord and knot at the top, and above all the sound. This guide covers each in turn, then explains what to look for when buying online and what to do if you suspect you already have a counterfeit.
The Laser-Engraved Letter O and Color Coding
The most reliable visual identifier of an original Koshi chime is the laser-engraved letter O on the bamboo tube. On a genuine Koshi, the O in the word KOSHI is not simply printed; it is engraved into the bamboo surface and filled with a color that identifies the specific tuning. The color coding is consistent across the entire Koshi range:
- Red identifies Ignis (Fire)
- Blue identifies Aqua (Water)
- Green identifies Aria (Air)
- Orange or brown identifies Terra (Earth)
This color is visible on both the chime itself and on the original packaging. The engraving has a precise, clean edge that reflects the laser process used in the original workshop. On imitation versions, the lettering is typically screen-printed or applied as a sticker. The difference is tactile as well as visual: printed ink sits on top of the bamboo surface, while laser engraving creates a depression that you can feel with a fingernail. Run your thumbnail lightly across the O on the tube. If it catches in the groove, the engraving is genuine. If the surface is smooth and the marking lifts slightly at the edge, it is printed.
The colored dot in the O also appears on the top flap of the original box, where it indicates the specific tuning purchased. On the left side panel of the box, all four melodies are listed, and the one you purchased is ticked. This detail is rarely replicated correctly on counterfeit packaging.
The Bamboo Tube
Original Koshi chimes use bamboo sections selected for uniform wall thickness and surface quality. The outer surface of the tube is smooth and consistent in color, with the natural grain of the bamboo visible but not rough. There should be no visible cracks, splits, or inconsistencies in the wall. The finish is applied carefully to protect the material against humidity without obscuring the natural grain.
Imitation versions frequently use lower-grade bamboo that shows surface irregularities: uneven coloring, minor splits at the nodes, or a rough texture from inadequate finishing. Some imitations use resin or plastic tubes painted to resemble bamboo. Plastic is immediately identifiable by its uniform surface texture and slightly different weight distribution; bamboo has a natural density variation that plastic lacks.
Run your hand along the length of the tube. A genuine Koshi feels consistent, slightly cool to the touch, with the subtle surface variation of real plant material. A plastic tube will feel warmer and more uniform. The genuine bamboo also has a slight variation in color along its length, reflecting the natural growth of the plant. An entirely uniform surface should raise questions.
The Resin Coating
Koshi applies a protective coating to the bamboo after assembly. This coating is matte, not glossy, and slightly darker than untreated bamboo. Its purpose is to stabilize the bamboo against seasonal humidity changes, which would otherwise cause the tube to expand and contract and alter the tension of the rods. The coating should be even across the entire surface, with no runs, bubbles, or bare patches.
On imitation versions, the coating is often absent, applied unevenly, or replaced with a glossy lacquer that gives the tube an artificially shiny appearance. A glossy tube is a strong indicator of a counterfeit. The original finish is understated.
The Metal Rods
Inside the bamboo tube, eight metal rods are suspended from the top cap. On a genuine Koshi, these rods are smooth, with clean cut ends. The tuning is achieved by cutting each rod to a precise length, and the cut ends are finished so that they do not scratch the inside of the tube or catch on the cord. When you look inside the bamboo from the bottom, the rods should appear parallel and evenly spaced, hanging cleanly.
On imitation versions, the rods may show rough ends from poor cutting, visible weld marks where they attach to the top cap, or uneven spacing. The metal itself may be a different alloy, which is visible in its color: the genuine rods have a consistent silver tone without discoloration. Some imitations use rods with a slight yellowish cast that indicates a different base metal.
The Cord and Knot Quality
The Koshi chime is suspended by a natural fiber cord. On an original Koshi, the cord is of consistent diameter, undyed, and finished with a clean knot at the top cap. The knot should be tight and symmetrical, not bulky or irregular. The cord exits through a small hole in the top cap that is clean and finished; there should be no fraying or adhesive visible around the exit point.
Imitation versions often use synthetic cord with a slightly waxy or plastic feel, or natural cord that has been poorly finished. The knot quality on counterfeit versions is frequently inconsistent, with visible fraying or over-large knots that suggest the cord has been replaced or retied rather than finished at manufacture. The loop at the top should be even; if one side is noticeably longer than the other, the cord work was not done with care.
Weight and Balance
An original Koshi chime has a specific weight and balance that comes from the combination of bamboo tube, metal cap, metal rods, and natural cord. When you hold it suspended from the cord, it hangs with a slight downward tilt toward the cap end, not perfectly vertical. This is a consequence of the metal cap and rods being heavier than the open bamboo end. The total weight of a Koshi is approximately 90 to 100 grams.
Imitation versions that use lighter rod materials or thinner metal caps will feel noticeably lighter. Those that use denser synthetic materials may feel heavier, but the balance will be different. Neither will hang or swing in quite the same way as the original when moved through air. A genuine Koshi has a characteristic slow swing that comes from its weight distribution; lighter imitations swing faster and settle more quickly.
The Sound Test
The most definitive test is the sound. Gently strike a rod or allow the clapper to contact the rods by moving the chime slowly. On an original Koshi, each note sustains for several seconds, with the overtones clearly audible alongside the fundamental pitch. The sound does not decay abruptly; it diminishes gradually, with the higher overtones fading first and the fundamental lasting longest. This slow, layered decay is a direct result of the precise tuning and the quality of the metal: the rods vibrate at their correct frequencies for a long time because there is minimal energy loss through imprecise cutting or poor alloy selection.
On an imitation, the sustain is typically shorter: one to two seconds rather than four to six. The overtones are less distinct, or absent entirely. Some imitation versions produce a slightly metallic buzz on certain notes, indicating either poor weld quality or a rod that is not correctly secured. Notes may also be slightly flat or sharp relative to the intended tuning, producing a sense of vague unease rather than the resolved consonance of the original.
If you have the opportunity to hear both side by side, the difference is unambiguous. If you cannot hear the chime before purchase, buying from an authorized reseller is the only way to guarantee you are getting the original instrument.
Testing in a Shop
If you have access to a physical shop: hold the chime by the cord with one hand and allow it to hang freely. Tilt it gently to one side so the clapper swings and contacts the rods. Listen for the sustain and the layered overtones. Then hold the tube lightly between thumb and forefinger midway along its length and tilt again: the sound will be damped slightly, but the quality of what you hear should still be clear and resonant rather than thin and abrupt.
Look at the bottom of the tube: can you see the rods cleanly? Do they appear smooth and parallel? Is there any visible debris, rough welds, or uneven spacing? Turn the tube to examine the engraving in different light: does the colored O have a crisp edge, or does the color bleed onto the surrounding bamboo surface?
The Original Box
Original Koshi chimes come in a specific rectangular kraft box designed to hold the chime securely. The box is printed in three languages: French, English, and German. The front panel shows the chime with the colored O visible. The top panel shows the chime's elemental name and its color-coded dot. The back panel carries text about the chime beginning with the phrase "be touched by sound." The left side panel lists all four melodies with the purchased one ticked. The right side panel repeats the Koshi name in a pattern with the colored O.
On the bottom of the box, the barcode of the original product is printed. Counterfeit packaging often omits one or more of these details, gets the language mix wrong, or uses slightly different proportions. The print quality on the original is consistent and sharp; counterfeit boxes often show slight blurring or color inconsistency.
Buying Online: What to Look For
When purchasing online, three factors reduce the risk of receiving a counterfeit. First, buy from an authorized stockist. Authorized retailers source directly from Koshi SAS and can be held accountable for what they sell. Second, look for product photographs that show the bamboo body clearly, including the engraved O, the top cap, and the original gift box. A seller who shows only a stylized product image without the box is not necessarily selling counterfeits, but the absence of packaging photographs is a gap worth noting. Third, read the product description: it should reference the Pyrénées origin, the specific tuning notes, and the elemental system. Generic descriptions that do not mention France or the four elements should be treated with caution.
Price is also an indicator, though not a definitive one. Genuine Koshi chimes have a retail price that reflects the materials and craftsmanship involved. A price significantly below that level suggests a counterfeit. However, a price at or above the standard level does not guarantee authenticity.
Where Authentic Koshi Chimes Are Made
Genuine Koshi chimes are manufactured exclusively by Koshi SAS in the Pyrénées Atlantiques department of southwestern France. No other manufacturer has the right to use the Koshi name or replicate its construction. Any bamboo wind chime sold as a Koshi that was not manufactured by Koshi SAS in France is a counterfeit product.
The Pyrénées Atlantiques is also home to the Zaphir chime workshop, which makes the Zaphir range: a related instrument with seasonal tunings. Zaphir chimes face the same imitation problem as Koshi. The same principles apply when evaluating authenticity: look for laser engraving, quality bamboo, correct weight, and above all the sustained harmonic sound of a properly made instrument.
If You Think You Have a Counterfeit
If you have purchased a chime that shows multiple indicators of being counterfeit, the options are limited. If the purchase was recent, return it to the seller on the grounds that it was not as described. If you purchased from a marketplace seller rather than a branded retailer, report the listing to the platform: most major platforms have processes for reporting counterfeit goods. If you are uncertain whether what you have is genuine, compare it against the identifiers in this guide. No single indicator is always conclusive, but the combination of several is diagnostic.
The complete Koshi range is available through this store. Each chime comes in its original kraft box with the Koshi trademark label, the color-coded O, the correct packaging text in three languages, and the engraved bamboo body. The set of all four Koshi tunings is also available at a package price for those who want the full elemental range.
