The other reviews are correct in stating that the crayons don't stay in the holders that they come with. Fine. We took them out. I gave my son two and I took one for myself so I could show him how they work. I wrote his 6 letter name on the side of the tub and the crayon was half gone! They crayons were dissolving in the water! What a waste of money. Fortunately I had also purchased the Crayola tub markers. Those are much more durable.
