First of all, these come in a great storage case. Each marker has it's own slot, and the case fold open and closed and secures with 3 closures. Two on the side and one on the top. The brush markers themselves are a lot of fun to "paint" with. Different than a normal marker, they make what looks like a brush stroke instead of just a mark. You can get as creative as you want and use them on most any medium. I like the feel of a sketch pad when I'm using them, but if you want, you can use a coloring book or just plain paper. It's a lot of fun for a small price.
