Suitable for organizing not just books but also CDs, DVDs, and more. Books adjacent to the one removed do not fall. It can be connected via joints on both sides. When books or similar items are inserted from the front, a stopper rises, and the stoppers on both sides hold the inserted item in place, preventing it from falling. Even if only one book is removed from several, only the stopper where the book was removed lowers, preventing adjacent books from falling, making it easy to know where to return the book. The back side is equipped with non-slip rubber feet.
