Vintage buttons from Riasutan. Beige, light brown, and dark brown layers are stacked, and the carving creates a beautiful pattern. These buttons have a beautiful kaleidoscope-like design. The thickness is about 4mm. I have been collecting Riasutan buttons little by little because I like them. 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.
