Add an interesting elements to your sketches, and make certain things stand out.

They only come in a limited few colors, but I always have white, black and red on hand -- they do add a nice change of mark in a drawing. For a really cool effect, try erasing them. It smears and blends it, resulting in an almost oil-paint kind of look.

Great for quick sketches and gesture. Unraveling it can be hard and needs patience.

IT writes spectacular on top hot thick burger boxes, havent quit introduced into my arsenal yet.

Perfect for marking glass and plastics before cutting. I cut my glass by hand so it works fine. Don't use them for much else though.

Good for marking things.

Love them - add top layer of cp drawings to finish the look I want

you can draw on anything with these!!
