I received two types of domestically produced bark from an acquaintance: Japanese mountain grapes and walnuts, so I handmade a rose-shaped charm. Considering the color, I think this is walnut, but I couldn't tell whether it was Japanese mountain grape or walnut, so I've labeled it as bark. Size: Diameter: Approximately 4cm, String length: Approximately 13cm Photos 3 and 4 are photos of the front and back. Please note that the actual color is a slightly darker brown. As this is handmade by an amateur, please purchase this item only if you understand the above.
