Grasping, biting, rolling, stacking, balancing, peeking through - the Ulu and Tulu shape sets from Moluk make all this possible. Bright colors and unusual shapes make them particularly interesting for small children as grasping and biting toys. Ulu elements do not roll away, but can be layered or pushed into each other. Tulu elements can be stacked on top or each other to form fantastic structures or strung together to form abstract queues.
