These are Showa-retro buttons. They have been carefully stored in a dark place. I checked them before listing them for sale due to long-term storage. I believe there are no scratches. The metal parts have discolored. I think they will shine if polished. Regarding the size, it is also a layman's inspection, so if you are concerned, please ask via message. Returns and exchanges are not accepted. ◆ Blue plastic square button, Showa retro button vintage button blue resin button Metal processed footed 18mm 2 pieces
