Rainbow Reveal Thinking Putty is a multicolor, tactile fidget tin that reveals a hidden rainbow of colors with three dramatic effects: it warms and shifts with your hands, morphs under sunlight, and glows after lights-out. Soft enough to stretch, sculpt and pop yet resilient enough to bounce and tear, this non-toxic silicone putty won’t dry out or leave sticky residue. Ideal for sensory play and strengthening hands and fingers, it comes in a 1/5 lb (3.2 oz) collectible tin and is labeled for ages 3+. Warning: contains small parts — choking hazard.
