This contemporary and elegant design of 3D wave block panels is a one-of-a-kind art formation. Made with faux leather and PU memory foam, each wave block measures (W)9.84" X (L)19.68" inches. The wave block pieces have a wave pattern on the outer face, available in white color, and all are self-adhesive. Just peel off the film and stick on the dust free wall. We suggest placing sticky glue tape or wall glue on the wall first, then applying the panels to the wall for firm support. You can purchase sticky glue tape or glue at any local hardware store. Then, simply design the shapes any way you desire. You can also easily cut and trim the panel with a utility blade, if necessary. These panels can also be used on curved walls. Best of all, this product is sound proof, fire resistant, and zero formaldehyde emission (environmentally safe). This product is sold in a 8 piece set. The 8 wall block panel pieces = 1m²(10.76 square feet). Bring any room, office, or lobby to life with this 3D modern design.
