Watercolor artists love this product. Similar to watercolor pencils, these watercolor crayons can be used with water and a brush. Pop this set into a gift set and it makes a great addition to a children's art kit. This product is also used on glass for restaurant menu boards. By over-laying the colors you can create a practically unlimited palette of intermediate tones. Kids art supplies lists have these tins listed by name because of their diverse usefulness. align=left>Privacy Policy.
