add-on set: curves

The Curves Set offers curvilinear shapes that add an element
 of whimsy, and allow children more opportunities for self-expression.

These complex, biomorphic forms give children much greater range for figuration, finer details and advanced structures.

The Curves boost the complexity of the children’s inventions: children make moving parts, structures based on connectors, and irregular compositions that require consideration of balance. The children are able to make more elaborate characters as well as props and accessories to fuel their dramatic play. The curved, ergonomic contours also invite more sensory and body interaction with the parts—children love to rock, ride-on and hug them.

Manufactured in the United States out of waterproof foam, the blocks are resistant to mold, mildew, corrosion, and microorganisms. Introducing breakthrough technologies, these highly durable parts are biodegradable and can be returned to the manufacturer for recycling.
