Hey there! Let's talk about using this awesome dolphin - themed floor wallpaper. First, measure your room to know how many square meters you need since it's sold per square meter. When you're ready to use it, pick the place on the wall or floor you want to decorate and wipe it clean. Before sticking, take a good look at the sticker to see how it'll look best on the surface. Then, start peeling the sticker from the bottom of the paper and stick it starting from the middle and moving towards both ends. This way, you'll get a nice, smooth finish. One thing to keep in mind is that there might be a little color difference between what you see on your screen and the real wallpaper because of monitor settings. Also, this wallpaper is waterproof and wear - resistant, so it's pretty easy to maintain. Just clean it with a damp cloth if it gets dirty. Enjoy decorating your room with this beautiful wallpaper!
