MYSTIFYING MERMAID
Appearing in the folklore of cultures all over the world, the mermaid has fantastical powers that work in mysterious ways. Mystifying Mermaid Thinking Putty® is just as spellbinding. Awash with sparkling shimmer, it transforms from light aquamarine to seafoam green with just the warmth of your hands.
As part of the Hypercolor® Collection this color change Thinking Putty is heat sensitive, meaning it starts one color and changes to another through heat transfer. The more you play the more the color will change!
