Much like how there are scratch and sniff stickers for children and scratch and sniff cologne/perfume ads in magazines that allow you to scratch them and reveal a beautiful scent of chemicals that smell like strawberries, flowers, and farts and stuff, these colored pencils are sketch and sniff pencils which allow you to draw and then smell your drawing to reveal different scents. Each pencil comes with it's own scent, including blueberries, vanilla, watermelon, coconut, grape, etc... and once you make a mark on some paper it will smell just like whatever smell is on the label of the pencil, or you could probably just smell the pencil directly, but what's the fun in that.
