For those of you who have been waiting for a set of serious crayons, your prayers have been answered. These are smooth, easily blended and loaded with pigment, which means that when you add water they really blend without losing the color. Plus, a little bit of this color goes a long long way. They are highly lightfast, which means there is very little change, even when exposed to museum quality light for over 100 years. They work great on paper, canvas, cardboard, wood, masonite, glass, plastic and leather for drawing, watercolor, encaustic techniques and more!
