Vintage buttons from Reastan. Green, light blue, and orange are layered, and the beautiful patterns are created by carving. They look like a kaleidoscope and are very beautiful buttons. The thickness is about 4mm. I love Reastan buttons and have been collecting them little by little. There are no noticeable scratches or stains, but there are some minor scuffs. I would be grateful if you could purchase them if you understand this.
