These appear to be old, colored glass buttons. There are 28 pieces in total. 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. There are also glass buttons with almost no coloring. Please check the photos for the detailed condition and size of the items. Please also read and agree to the contents of the profile section. We look forward to your purchase. *Toshitaka Tada's "Toy Museum 18: Girls' Toys" mentions on page 3 that "O-hajiki (glass game pieces) were made from repurposed materials such as glass buttons" due to wartime shortages. It is unknown whether this item is related.
