It’s about time the crayon was reinvented. Clementine Art Supplies has developed the kid friendly Crayon Rock, especially designed for little hands. Using only natural, nontoxic, and mineral and plant derived pigments; these colorful gems are worth the hype, as they are made from nature, without harsh mystery chemicals. Initiated by a concerned art teacher in lovely Boulder, Colorado, Clementine Art Supplies was started to make sure our children aren’t being introduced to anything that they shouldn’t be (we all know you enjoyed a little crayon snack every now and then). This 9 color crayon rock set is perfect for coloring (paper, not walls, please), playing around, or making masterpieces.
