There have been a lot of shelves, but none reflect literature quite as well as the A-Z Bookends.
The A-Z Bookends were designed by Jochen Korn, who decided to add the alphabet detail as a complement to appeal to those who just can't get enough of words. The shelf is made from a special concrete, which is perfect because you'll know that it's secure and that it'll do its job just fine. Both ends have the ABC's carved into them, which is a nice nod to the items it's supporting. Of course, like any bookend, there's an extended base on the bottom to support itself and the first couple of books you have.
There are two versions of the A-Z Bookends, with either the "ABCD" or the "XYZ" as an design option.
