Using these press-on nails is easy. First, clean your natural nails thoroughly to remove any dirt or oil. Then, choose the right size of fake nails from the 24-piece set. Peel off the duo-side adhesive sticker and attach it to the back of the fake nail. Press the fake nail firmly onto your natural nail for a few seconds to ensure it sticks well. When it comes to maintenance, avoid using your nails as tools to prevent them from coming off. Also, try to keep them away from excessive water, as this might loosen the adhesive. If you notice any lifting, gently press the nail back down. And remember, these nails are designed for finger use only. Have fun with your new fashionable nails!
