One set includes Twelve SOLARTRONIC Sticker Cards. Based on a collection of classic SUCKADELIC characters, each image is printed on a heavy card of "Zapping" metallic foil that sparkles in Sunlight. Each card has a peel away film to reveal an adhesive back for Sticking! For less than a buck each you can't really complain. If it's from Suckadelic you know it's quality.
