These shoe buttons can be used for clothing, dolls, teddy bear eyes, jewelry making & anything you can dream of. The buttons are 8mm round & are solid black. 25 Pair. These shoe buttons are from my Great Grandfathers Shoe store in NYC in the early 1900s. They have been in our attic for years & I used them for crafts as a kid because we have so many of them. I don’t know what material they are. I broke one open with a hammer & it looks like painted wood or sawdust, but they are all perfect & consistent in shape & size.
