Using your Angel Aspera Anime Girl peeker sticker is easy. First, clean the area on your car where you want to place the sticker. Make sure it's dry and free of dust. Then, carefully peel the sticker from its backing and apply it to the desired spot, smoothing out any air bubbles as you go. As for maintenance, you don't need to do much. Just wash it with mild soap and water when it gets dirty. Avoid using abrasive cleaners or scrubbing too hard as this could damage the sticker. And since it's weatherproof, it can stay on your car in all kinds of weather conditions, but extreme heat or cold might affect its adhesion over time. If you notice the edges starting to lift, you can use a little bit of clear tape to secure them.
