This is essentially a large multi-colored ink pad, so we set out a cup of water and set aside a paper towel so my kids could wash and dry their fingers off between stamping their prints in the included art book. The book encourages creativity and has been a blast for them thus far. I’m worried that the ink will dry out quickly but my kids have put shoe fingers i the water and then stamped the pad in places they felt it was more dry and it has worked great! I bought this for an activity for my 4 and 6 year old to do so that they can avoid all the screen use. It is a great buy.
