Umbra Conceal Floating Shelves, Set of 3Conceal Shelves come in a set of 3 powder coated silver floating bookshelves that become invisible behind a stack of books, transforming the books into a work of art. The shelves have flexibility in the mounting formation and can be displayed as a group or separately, linear in orientation or staggered. Conceal has a small lip to hold the book cover from falling and give off the illusion of a floating shelf. The set is space-saving and can fit into awkward wall spaces to securely nestle your books. Coming in a sheen silver finish, Conceal can integrate seamlessly into any space, adding dimension. The small shelf size measures at 5 x 5 x 5 ½ inches (13 x 13 x 14 cm) and hold up to 15 pounds (7 kg).
