ooly chalk-o-rama chalk crayons, 12 colors

Dust-free chalk sticks that work on many surfaces but feel like a waxy crayon.
Great colors that are permanent on porous surfaces like paper, but
wipes off easily on non-porous surfaces like glass. They work so well on black paper, and on windows! Mess free these chalk crayons are encased in plastic barrels with twist up action. Set of 12 colors. Suitable for children 3 and up.
