My daughter really likes these and enjoys smelling each of them as she uses them. The little stamps are so cute. My only complaint would be that the caps on the stamp end are so small that they are a little hard to grip to remove.
I admit I may have been more excited about these than my toddler but he loves them as well. They clean up easily from the kitchen table. I have not tested washing it out of clothes yet though.
My son is four and doesn’t seem to have any trouble keeping up with the kids and taking them off.
