These are so interesting and cool! Vintage Japan handmade 3d glass eyeballs on wire, perhaps originally intended for use in doll making. Due to handmade nature, there is variation in size, shape, and color placement. Eyes range in size from 14.5-17mm in length and are about 13mm in height and depth. Wire gauge is likely 21 (.7mm) and the lengths range from about 30-35mm. The wire is also very flexible but does show some discoloration due to age. Metal content of wire is unknown.
