Bring a flutter of spring to playtime with a sun-activated mini putty that shifts from blue to purple when exposed to sunlight. This tactile, non-toxic silicone putty (0.47 oz tin) is designed for stretching, bouncing, popping, tearing and sculpting — great for fidgeting, sensory play, and hand-strengthening exercises. Packaged in a collectible mini tin, it’s small enough for stocking stuffers, party favors, or on-the-go calming tools; includes standard safety warning for small parts and is recommended for ages 3+.
