These are large, thick, and now rare, Showa-retro butterfly shell buttons. They can be used as craft materials, such as gluing them together with adhesive to make a brooch, stringing them all together to make a bracelet, or sewing them onto a Christmas tapestry like snow. The shell has a beautiful shine and a substantial weight. How about using them as craft parts instead of buttons? Diameter: 2cm, Thickness: Approximately 3mm The same size as a 50-yen coin. Please compare them with a 50-yen and 100-yen coin. There are 70 pieces.
