Set of 12, Vintage Crystal Beaded 1" Buttons from Japan, Super Sparkly, #VB-22

From Japan, they are covered with very sparkly silvery-clear beads. We assume the buttons are handmade and the beads are glass.  Maybe 1950's?  They have a small silver-color shank and off-white silk backing. We think this is the original tying with natural, maybe hemp, string. The buttons are 1" diameter, about 1/4" thick and as you can see, the edge sparkles with beads, too. Fancy and fabulous, clearly higher end. Despite the photos they are glistening crystal-y silvery white with fine fine detail, not at all gray or beige.  You'll get one tied sparkly bundle, with 12 buttons. Japan.
