Milky Way Sparkling Thinking Putty
This is one of the coolest puttys around! MILKY WAY is a glossy purple putty filled with glow in the dark glitter. The glitter speckles glow when activated with the glow charger (included) or sunlight! Stretch it, twist it, shape it and watch the night sky come alive in your hands! It never dries out.
