Invisible Bookshelf From Umbra

Whether you're into James Joyce or James Patterson, the Conceal Book Shelf is a must-have for any serious bibliophile. Create a unique and attractive wall display, plus store your book collection with the Conceal Invisible Book Shelf. Your books will appear to be floating in mid-air, because this bookshelf is invisible behind a stack of books.

Installation is simple; just screw the Invisible Bookshelf into a wall stud with the included hardware. To stack your books, place the back cover of the bottom book between the bottom of the shelf and the small lips beneath the shelf, then organize the rest of your books on top. The Conceal Invisible Bookshelf features super strong steel construction with a silver powder-coat finish for extra durability.
