The Kitpas Bath Crayons 10 Colours (white, pink, red, orange, yellow, green, blue, violet, brown, gray) with Sponge are specially formulated crayons designed to be used on wet surfaces such as bathtubs. Not only are they hexagonal in shape for slippery hands but the crayons can also float in water for safekeeping and the paper that encases the crayons is waterproof for extra durability.
Kitpas Crayons are known to be buttery smooth, vividly coloured, water soluble, completely non-toxic and easy to clean. All you need to do is simply wipe over a few times with a sponge and rinse with water.
