Apply to a smooth, clean, dry surface, free of grease – we recommend using isopropyl alcohol. Apply to easily visible places. Before applying, adjust the size as needed. Do not touch the sticky part so as not to degrade the adhesive properties! The adhesive property of the stickers is reduced on matte surfaces! If necessary, clean the dirty stickers with a damp cloth. Store the package in a clean, dry place at room temperature, away from direct sunlight. This product is not a toy.
