The Skin Book is a delightful activity book that invites you to unleash your inner tattoo artist on irresistibly inviting synthetic skin pages. The brainchild of Brazilian publication Tattoo Art Magazine, in collaboration with the Lew/Lara TBWA agency, the limited edition sketchbook lets budding tattoo artists mess up on its polymer pages instead of an actual human skin.
The pages even feature images of real body parts, to help make practice feel even more real. Unfortunately, the book includes no private parts, so you're still going to have to draw that little Pikachu on your scrotum.
