Putty Peeps is an amazing new putty that has the properties of both solids and liquids. When you play with the putty, it is heated up from the warmth of your hands and it will behave just like any other solid putty - stretch it, shape it, squish, snap, and bounce it. However, when this putty is left to sit, it will begin to lose the shape you molded and will appear to melt without being wet or sticky! You can really start having some fun with the included original Putty Peeps eyes and black light! Putty Peeps Light Effects have the ability to change colour under sunlight or the black light. Putty Peeps use silicone technology to give them their unique properties, and are non-toxic and never dry out.
