These writing utensils are amazing to draw with and feel great in the hand.
This series features weapons: a 30mm shell, an AK-47 and "Little Boy." The text on the box reads: "This [weapon] will change into words and pictures with normal use. Drag [weapon] across paper until poems and drawings appear. Continue using until [weapon] disappears."
Each comes in a specially designed box and lasts approximately eight years with normal use.
