I am selling several items related to kimonos, such as obi clasps, obijime (sash cords), obiage (sash scarves), and obis. These are old items. They are natural stones, but it is unclear whether they are onyx or something else. I will include an obijime as a bonus, so please comment if you would like one. Approximate size: Height: 1cm 3x1.5cm There is a chip on the back, as shown in the last photo. ★Please be sure to read the profile along with this before purchasing. I generally do not negotiate prices, but for those who purchase two items (two listings) and wish to combine shipping, I will offer a discount to cover postage and other costs. Please comment with your desired price. These items have been stored at home by a non-professional. Please only purchase if you understand this. The colors may appear slightly different due to the lighting during photography. There may also be other areas that I have overlooked. Please refrain from purchasing if you are concerned about minor details or are overly sensitive. Everything is as shown in the photos. If you would like to confirm something, please comment and I will add more photos or confirm details. I cannot answer questions about the items, accommodate shipping requests, or specify delivery dates after purchase. Please be sure to confirm everything before purchasing.
