The biggest highlight of this bookshelf is that it can be combined. It always looks more varied because there are two types of bookcases instead of a single bookshelf combination. Put 2-4 bookshelves together, it will look like a bookshelf wall, which looks more grand and elegant in the living room. The bookshelves can also be used as kitchen shelves and display cabinets. The 71-inch Wood color bookcases measure 15.7"D x 23.6" W x 71"H. The Style A bookshelf contains 3 large drawers with silent slide rails and 3 open shelves. The Style B bookcase contains 2 cabinet doors and 2 tempered glass doors. The storage cabinet is made of high-quality MDF and selected high-quality hardware accessories. The bookcase has strong load-bearing capacity, structural stability, and durability. The surface of this cabinet is finely polished, smooth, and easy to clean. It is also equipped with an Anti-toppling Device. This bookcase requires assembly.
