Using these wall stickers is super easy. First, get the template and fix it to the wall as the instructions say. Look for the numbers on the template and tear the paper following the dotted lines. Take your time to stick the wall stickers into the hollows of the template carefully. After that, peel off the protective film. When you're done with that, just tear off the template. As for the color, keep in mind that because of different monitor settings, what you see on the screen might be a bit different from the real thing. To maintain these wall stickers, avoid using abrasive cleaners. A soft, dry cloth is enough to keep them clean and looking great. And remember, since they're waterproof, you don't have to worry too much about a little moisture, but don't let them soak in water for a long time.
