Using these wall stickers is easy. First, clean the wall surface where you want to apply the sticker. Then, carefully peel off the backing paper and stick the sticker onto the wall, smoothing out any air bubbles as you go. When it comes to maintenance, you can gently wipe the sticker with a dry cloth to keep it clean. Avoid using sharp objects on the sticker as it may damage the surface. Also, make sure the wall is dry before applying to ensure better adhesion.
