Keep away from small children, beads can be a choking hazard. Keep out of mouth. Not a toy.
Pens are refillable, replace the cartridge when it runs out!
Clean regularly by wiping with a soft, dry cloth; avoid soaking or using harsh chemicals, which can damage beads and glue. Store pens horizontally or tip-down, securely capped or retracted to prevent ink drying, and keep away from extreme heat.
