Although this item is new and unused, it has been stored at home for a long time. Part of the non-slip sole on the bottom is peeling off. It might be repairable with glue, but I haven't tried it, so I don't know. Also, since it is an old item, there may be some damage due to aging. The size is not listed, but the length is about 24cm. I tried it on, and it fit perfectly, and I usually wear 23cm shoes. The width is about 8cm, and the thickness of the sole is about 3cm (heel part). The material is described as "yakisugi," so I believe it is made of wood. When shipping, the item will be taken out of the storage bag (the bag is not included) and will be simply packaged to prevent water damage.
