Tulu

With its elegant geometry, Tulu feels as timeless as a Brancusi sculpture — yet it’s designed for hands-on discovery at every age. Perfectly sized for little hands, it’s an inviting first grasping and teething toy for babies. As children grow, Tulu rolls, stacks, and balances, turning balls into towers or acting as the “missing link” in imaginative constructions and pretend play.

Thread a string or cloth through its open form for active play, or combine it with other MOLUK toys: turn it into wheels for a Bilibo Mini car, stack it with Mox balls, or seal both ends to create a giant suction cup that anchors a Bilibo Mini to bathroom tiles.

Crafted from soft, food-grade silicone, Tulu is safe, silent, and endlessly versatile. It engages the senses, builds fine motor skills, and inspires creative problem-solving — proving that the simplest shapes often hold the most possibilities.
