Monkey Toes are hand painted, with non-toxic paint, but it is preferable that they not be chewed on. It hurts! They can be worn outside, even on rainy days. Please wipe off with a damp cloth instead of placing in the washing machine.  Monkey-Toes come in children's sizes 1 through 10. However, they tend to run a bit big, so please refer to the sizing chart before ordering.
