Seahorse Tub Tattoos These little non-slip Seahorse treads make bath time safer and more fun! Each package contains five non-slip Seahorse Tub Tattoos. They're easy to install and easy to clean. Just peel and stick! For use on non-textured surfaces. Use on textured bathtub surfaces will allow water to get beneath the adhesive and will shorten their lifespan. 4" diameter. We recommend 3 to 5 packages for full tub coverage. Mix and match with other popular styles of Tub Tattoos!
