Curves feature four distinctive textures and four bright colors that invite patterning as toddlers create geometric shapes and build simple structures. Faces on the ball connectors encourage toddlers to create expressive characters and engage in dramatic play. Children learn best through self-directed, open-ended play. Grippies Curves invites such learning. Compatible with the original Grippes Builders.
