DURO Oil Pastel Wax Crayons - 24 Assorted Colors We love oil pastels here at the arts and crafts center of the surplus world. Sort of crayons, but with a little blendability thrown in for your drawing pleasure. The pack has white, rust and black, plus a range of yellow through red and green through blue. All are 2-3/8" long and all are from Duro.
