Tombo dama is the ancient Japanese technique of meticulously crafting glass balls or beads with patterns embedded in them. These pins feature simple but striking half-and-half tombo dama balls, each beautifully finished by hand. The pins themselves are copper with nickel plating, and a package includes 10 one-and-a-half-inch pins in a rainbow of colors, perfectly suited for all your rainy day projects and for gift giving!
