Birth & up. Soft and durable, Indestructibles are chew-proof, rip-proof, nontoxic and 100% washable. Indestructibles are books built for the way babies “read”: with their hands and mouths. Chew-proof, rip-proof, and drool-proof, they’re printed on a unique 100% nontoxic, paperlike material that holds up to anything babies can throw at it—gumming, spilling, dragging across the floor. Indestructibles are the little books that could. And if they get dirty, just wash them off. This set includes basic concepts like opposites, colors, shapes, numbers, outdoors, seasons and kindness. Each has bright illustrations that capture the attention of infants and toddlers.
