This adorable necklace features library book shelves with vibrant colored books. The silver-plated pendant tray is approximately 1 inch, and the faux leather necklace cord is 20 inches long, with a silver plated, nickel-free clasp. This is a wonderful gift for a book lover or a library lover! The necklace also features a small, open book charm. You can wear the book shelf pendant or the open book charm alone on the necklace, if you slide the other charm off the necklace cord.
