This is a face button. It's carefully made with chamfering done meticulously, taking time and care. It goes well with clothes and bags made from old cloth (*^.^*) It's about 4mm thick. It may appear darker than in the photos. Please understand that this is handmade. Price is not negotiable. Because natural wood is used, there may be cracks, splits, or warping. I've included photos of both the front and back, so please use those to make your judgment. Returns and exchanges are not accepted.
