Let's start with using this waterproof 3D seashell and starfish mural. First, pick the place where you want to put it, be it a wall or the floor. Clean the surface well so the sticker can stick properly. Before you start sticking, hold the sticker up and figure out the best way to place it to make your room look great. When you're ready, peel the sticker from the bottom of the paper and start applying it from the middle out to both ends. As for the size, remember the price is for 1 square meter, so measure your room to get the right amount. The mural is seamless, which means it'll look smooth when you put it up. Also, it's waterproof and wear - resistant, so it can handle a lot of use. Just a heads - up, because of how different monitors show colors, the color on your screen might be a little different from the real mural. To keep it in good shape, avoid using harsh chemicals when cleaning it. A gentle wipe with a soft, damp cloth should do the trick.
