I bought this new, but I'm selling it because I'm changing the atmosphere of my room. TT I used it before, so there's double-sided tape attached, but it works fine. Dimensions are 30cm x 30cm. Photos 6 and 7 are pictures of it in actual use. 3D Wall Panel Wall Decoration Lightweight Waterproof PVC 3D Embossed Board DIY Living Room Bedroom Store Office White 30-piece set
