I found these wax crayons from the Manley company when I was looking for a white crayon to use for wax resist. I bought a 6 crayon box for a few centimos. They are super bright and blendy, almost like oil pastels, but not oily. Sort of silky like Amos “silky crayons” but not water soluble. None of the weak-willed color crayons usually give. They come in little six crayon boxes (black, white,red, yellow, green and light blue?) and in big metal tins. We went back for the 48 pack.
