Books on a wall. Just books on a wall. That’s all you (and your stupefied guests) will see. No huge shelves, no waste of space: just simple, elegant invisibility. Your books will appear to be floating on this wonderful easy-to-set-up bookshelf. All you need is a screwdriver and a wall. And books.

It can hold up to 15 pounds worth of literature, while still looking like it’s not there. As strong as it is thin, the shelf will stack your books as high as 16 inches. Buy more and build your own invisible tower.
