Shrink film is great fun to craft with. There's a lot going on! These sheets of shrink oil are already pre-printed with unicorns, an elf and a rainbow. All you have to do is color them and cut them out. Decorate the smooth surface with permanent markers and the matte surface with colored pencils. After you have finished coloring, cut out the figure and heat it in the oven. The plastic shrinks in size by up to 40%! Wow! If you poke a hole in the figure in advance, you will have your own key ring made of sturdy foil afterwards. The sheets measure 10.5x14.5 centimeters. Includes instructions.
