Create your own custom library, store and display your favorite cookbooks for easy access in your kitchen, or create a unique display that’ll be sure to earn you your share of “ooh’s and ‘ah’s”. Introducing Conceal Bookshelf Collection by Umbra. Conceal wall shelves have a small lip to hold the book cover from falling and give the shelves that “floating’ look. The collection works best with a hardcover book at the base of your stack, as it will make for a more secure bookshelf and the cover will be more secure on the lip. Also, be sure to stack enough books to cover the shelf mount on the wall. Alternate Use: In a bedroom cramped for space you can fasten a large Conceal to the wall, creating a tabletop surface bedside for your nighttime essentials. Conceal comes in a silver finish and looks great in a variety of spaces.
