Cracked glass beads: Approximately 8mm Tonbo-dama (lampwork beads) [Yellow-green]: Approximately 10mm * Can be used as a strap, or attached to zippers on bags and pouches, or as a charm. * The tonbo-dama is a glow-in-the-dark type that stores light and glows in the dark. * Tonbo-dama and hotaru-glass beads are made by artisans who melt colored glass one by one, wrap it around an iron core, and layer silver foil onto the molten glass like syrup, using a special technique to express beautiful colors. * Because artisans make each one by hand, there may be slight differences in size and color. * Please read the profile for precautions when considering a purchase. #Charm #Strap #Keyholder #BagCharm #ZipperCharm #MaskCharm #Beads #GlassBeads #Tonbodama #Hotaruglass
