Here are two Black Walnut Credenzas being delivered to Manhattan today. They feature solid slab construction with veneered doors with no hardware visible on the exterior. The doors push to open. Drawers are constructed of dovetailed matching walnut.
The smaller Credenza (two doors) is for a living room and serves as a bar- see interior below.
The three door Credenza (interior pictured above) is destined for a Dining room.
