This set of 12 different colours of transparent glass balls for decorating jewellery is used, for example, to decorate jewellery made from crystal resin. You can cast these small translucent beads into the resin to decorate a ring, bracelet or pendant, for instance. However, the beads can also be used for other jewellery-making techniques. The special box has a separate compartment and opening for each component, so you don't need to worry about the colours getting mixed up.
