If you have books and have no space for a shelf this hang-up book holder from Chiasso.com is a perfect solution. It creates the illusion of a line of books hanging vertically, unsupported on the wall and is thus an invisible book shelf! It’s comprised of a simple aluminum bracket with a plastic comb that grips the cover and pages of paperbacks. Simply mount the bracket on your wall and attach your books for a modern, suspended display on the wall. Use two or a few to create your own floating library. Mounting hardware and instructions are included. Paperback books only. Holds up to 20 lbs.
