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. They are buttery smooth, vividly coloured as well as water-soluble too - just add water and it instantly turns into watercolour paint. Safety & Usage: Recommended Age: 3+.
