Using these press - on nails is a piece of cake! First, gently push the edges of the nails with the manicure stick to get rid of any excess, then use the prep pad to clean the nail surface of moisture and oil. Next, pick the right nail size for each finger. After that, stick the adhesive inside the nail piece and peel off the protective film. Place the nail piece on your nail and press firmly for 15 seconds. Remember, don't let your nails touch water for 2 hours after applying. If needed, you can file the nails to your desired shape. To keep these nails in good condition, store them in a dry place when not in use. And when you want to remove them, just do it gently to reuse them later.
