Make bath time fun with Bathtub Crayons. Bring out your child's creativity and imagination with Bathtub Crayons! Create masterpieces on your bathtub wall! Bathtub Crayons are completely washable, making cleanup hassle free. Simply wipe down the wall with soap and water and the colors come right off! We recommend not putting bath crayons directly on towels or clothing. Do not let bath crayons soak in bathtub water. Bath Crayons must dry out after each use.
