Watch colours swirl and gears click into motion with a simple twist of the wrist. This 3D-printed heart-shaped design hides a set of interlocking gears that spin smoothly together, making it endlessly satisfying to fidget with, display on a desk or tuck into a pocket for on-the-go stress relief.

Measuring approximately 7 x 6.6cm, each piece comes in an assorted style and colour, so no two are exactly alike. Suited to curious hands aged three and up, it's a fun little sensory gift for kids who love to touch, turn and explore — just note it contains small parts and isn't suitable for children under three.
