Our nail glue contains polyurethane-10 and glycerin. It uses an innovative fast drying formula that cures quickly, saves time, and instantly displays perfect nail art results. The unique anti-flake formula closely fits the nail surface and finger deck, keeping the nail intact for a long time without worrying about daily wear and tear. Its use is simple: rough the surface of the nail. Apply the glue evenly to 1/4 of the nail, making sure there is enough. Press the nail from inside to outside to make sure it is flat and free of air bubbles. Press the nail for 30 seconds to make sure it is firmly fixed. Avoid contact with water for 4 hours and wait for the glue to dry completely. And it can easily cope with various nail designs with professional-grade bonding strength, ensuring that the finger deck is stable and does not shake, showing a lasting and beautiful style.
