The “cool” color is already coming back! Phantoms The phantoms have two very special properties. As soon as UV light hits the putty, it suddenly changes color. This doesn't just happen in sunlight, you can even paint on the modeling clay with the included UV lamp. After a short time the color fades again. In addition, the putty glows in the dark after it has been charged in the light. Glow in the Dark Glow in the Dark clay is mesmerizing and simply irresistible! Milky white in daylight, their glow magically appears when you dim the lights. The putty is transparent, the glow seems to come from deep inside!
