It's the little series that could: Indestructibles are innovative books built for the way babies read. Printed on a unique, nontoxic, paper-like material that holds up to anything babies throw at them, Indestructibles are rip proof, chew proof, drool proof and gum proof. They’re 100% baby safe—and they’re washable. When a book gets dirty, just throw it in the dishwasher or washing machine, and voilà, the book is back and ready for more.
