The box clearly shows a child fingerpainting on the shower wall....in no way could we make this happen. This stuff is like soap and smears around, do not buy for this reason or I hate to say I told you so."Alex bathtub fingerpainting kit" I don't know how much clearer it can be that it's a fingerpainting kit, but in no way shape or form is it a fingerpainting kit.There are ZERO instructions in the kit, only a brief notation that it may not come off on porous surfaces on the box and the bottles.DO NOT BUY THIS!!!
