Tonbo-dama [Blue]: Approximately 12mm * In addition to using it as a strap, you can also attach it to the zippers of bags and pouches, or use it as a charm. * Tonbo-dama and Hotaru glass are made by artisans who melt colored glass one by one and wrap it around an iron core. They then layer silver foil on the glass, which is in a molten state like syrup, and express beautiful colors using a special technique. * Because artisans make each one by hand, there may be slight differences in size and color. * Please read the profile for notes on purchasing. #Charm #Strap #Keyholder #BagCharm #ZipperCharm #MaskCharm #Beads #Tonbodama #Hotaruglass
