Our 3 tier shell art shadow box wall décor will light up your entire home/office space with its unique design. Two kinds of shells were heavily used to create the 3-tier centerpiece of this wall décor: auger screw shell and serpent’s head cowrie shell (over 400 shells in total). Shadowbox has a densely woven linen backing and a sturdy wooden frame. With its exceptional built quality and strong presence, it is ready to elevate any room to a new level of sophistication.
