Children love tattoos! Tattoos are a great way to keep The OrganWise Guys health messages alive for days after the actual lesson ends! They are also the perfect incentive item. These temporary tattoos are applied with water, last for 5-10 days (even while kids are swimming in chlorine, salt and fresh water) and are easily removed with baby oil or common household rubbing alcohol. The tattoos come in packs of 100 each.
