Rip Proof. Chew Proof. 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. And if they get dirty, just wash them off. Beloved by babies and their parents, Indestructibles were invented by Amy Pixton, a mother of triplets, after bits of traditional board books found their way into her babies’ mouths.
