It’s like magic! Make realistic pretend boo-boos appear then press on a bandage, pull it off, and the boo is gone! Because the boo-boos are made from a special material, there is no ink involved and the boo-boos can be reused again and again. No more wasting real bandages, this is even more fun than the real thing! Wet skin with the water pen, apply a boo-boo and brush on more water to make the edges disappear, and just the pretend boo-boo shows on skin. The pretend cuts and scrapes look realistic on all skin tones!
