With over two million copies in print, Indestructibles are the books built for the way babies read. They are 100 percent baby-proof, chew-proof, rip-proof, and drool-proof. Printed on a unique 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. They're indestructible. And if they get dirty, just throw them in the dishwasher.
