These appear to be old, colored glass buttons. There are 30 pieces. Some buttons have holes that were not properly made, so it's possible they were intended as toys for children. Some items have cracks or chips. Some glass buttons have almost no coloring. Please check the photos for the detailed condition and size of the items. Please read and agree to the contents of the profile section. We look forward to your purchase. *Toshitaka Tada's "Toy Museum 18: Girls' Toys" on page 3 mentions that "O-hajiki (glass game pieces) were made from repurposed materials such as glass buttons" (due to wartime shortages). It is unknown if this item is related.
