Our nail ball care oil contains glycerin and aloe leaf extract. It can be used to continuously lock in moisture and help keep the cuticles moist. Vitamin E moisturizes and repairs nails, making nails smoother and more shiny, and giving off a natural shine. Its application is simple: gently roll the oil roller over the cuticles and nail areas to ensure even coverage. Gently massage the oil into the skin with your fingers to help lock in the moisture. And the roller ball design evenly spread the oil, both convenient and efficient, not wasting every drop.
