Send your little explorer on a delightful sensory adventure of spinning and vibrating. Each spinning spinner is made of 100% high-quality, colorful, pleasant to the touch and safe silicone. So don't worry if your little adventurer decides to use the spinner as a teether - it's completely safe. Hold them, explore the unique contours of the spinners, or just let them soothe sensitive gums from teething. Then stick them to any smooth, flat, non-porous surface - a bathroom wall, a table or a window - spin and... watch how fast they spin, faster than the eye can see. With these fast, whirlwind spinners, sensory exploration becomes even more interesting and varied.
