It is a convenient premium sticker. Simply peel and stick gently by hand to any smooth, clean, dry and dust-free surface. If there are air bubbles, you can use a scratch card to remove them or use a needle to pierce small air bubbles and smooth them out. It does not affect the overall paste effect. If the side of the sticker is slightly curled, please use a hair dryer to heat the adhesive slightly and press firmly. Make sure the walls are smooth, clean, dry, and free of dust. When removing the wall sticker, use a hair dryer to heat the adhesive, then use a knife to gently lift the corner of the sticker and slowly peel it off. Because the packaging method is rolled, after you receive the sticker, unfold it flat, put something on it and keep it flat for a while, it will help it stick.
