What age is Our 12-Piece rainbow suitable for? This is a question that I regularly hear. either way. So from what age it is recommended and up to what age. Personally, I think he can be fun for children from one and a half years. They can discover and play with it. It is a toy that can take a beating and it has no small elements and is therefore not dangerous. The paint is also non-toxic, so putting it in the mouth is no problem. As your child gets older, it can do much more with it.
