Micador Dark Arts, Glow Paint Pens Set, 6-Color Pen Set

These Glow Paint Pens are great for paper, wood, fabric, plaster, canvas and more. The glow-in-the-dark pigments contain phosphors that absorb UV light photons and hang on to them, slowly emitting new photons with much lower energy. Store with cap tightly secured in a cool, dry place. Use Magic Black Light for full effect.
