A set of phosphorescent shrink foils that glow in the dark can be used to make keyrings, magnets, badges, original earrings or smaller decorations. First you paint a design onto the foil, which then shrinks to roughly 1/2 to 1/3 of its original size and becomes firmer when heated in the oven (smaller creations can be heated with a hot air gun). For working with shrink foil, we recommend using acrylic markers or coloured pencils — ideally black for this variant. You can finish the completed piece with clear varnish or cast it in crystal resin. The pack contains 3 sheets measuring 26 x 20 cm and a magnetic strip, which you can stick the finished piece onto and display it — on the fridge, for example.
