Our 21 month old loves it! He paints only with our 100% supervision, of course. Compared to crayons the colors are more vibrant, and he likes different textures this set provides. He enjoys smudging it right after application sometimes - very excited about that! Easy clean up, to -- doesn't get too messy. I will say though -- they seem to get to an end pretty quickly (the plastic container is a bit deceiving in size). Three of favorite colors from different set were gone in like 1 month (we do paint almost every day though!)
My 4 year old and 1.5 year old love these. They don’t have to push hard to get lots of vibrant colors. They easily wash off the floor and walls too.
