This is a simple but smart bookshelf design by Miron Lior. Conceal Bookshelf makes your stack of books look floating in the air without any support under the books. The bookshelf itself is only a powder coating steel that will becomes invisible behind stack of books. It can hold up to 15 lbs of weight. To use it, you must place a big book as the base, book with hard cover is better. You can buy this bookshelf here. This will looks interesting in your house right?
