Lots of binders and because of that sometimes the pigment doesnt come out. Really hard to work with. BUT, if you scratch them and then rub that powder for a simple background, like in a coloring book, they work. Is the best way you can some use of them. You are WAY better of buying a Mungyo Soft Pastel set. A little bit more pricey but worth every penny. Dont waste your money on this. Not even for kids!
