Invisible Book Shelf

These bookshelves are shelving and wall art in one. They seem to work by clamping onto the bottom book, securing it into place so that other books can be stacked on top of it, rendering the shelf completely invisible. If your book collection consists of a lot of paperback mystery novels, this may not be the optimal shelving because the display is much more appealing with hardback books. If your decor tends more towards minimalism, or if you already have stacks of display-worthy tomes, this unique design option may be one you want to consider. The shelf can support a weight of up to 15 pounds. Price: 18€
