Query: Not worth it

The crayon is in a plastic tube, which makes it seem more durable, but my 20-month old son quickly figured out how to raise and lower the crayon, then would try to write on the tub and the crayon would immediately break. He'd raise it higher and it'd break again. They lasted through 2 baths. The crayon is way too soft and it's too easy to raise and lower the crayon.
