【Excellent Emery Board Nail Files】 Perfectly sized at 7.09 x 1.10 x 0.16 inches, these nail files are made with Korean sandpaper, ECO sponge, and a strong PP board. They're not only high-quality but also healthy and safe for your skin. 【Versatile Emery Board Functions】 The 100 grit emery board is ideal for filing and roughening acrylic nails, dog nails, and hard toenails. 180 grit is suitable for fingernails and cat nails, while 240 grit smooths the nail edge with refined shaping. 【The Best Choice for Nail Files】 Our nail files are easy to rinse with water, making them more durable. The Korean-made sandpaper leaves barely any color on your nails. The thicker design makes them harder to break and more comfortable to hold. Plus, the wider design makes them more efficient to use. 【Multiple Uses】 These professional nail files can be used to remove acrylic nails & dip powder nails, remove cuticles, poly nail gel & gel nail polish, shape fake nails, and perform manicures and pedicures. Suitable for pregnant women, frequent travelers, nail art enthusiasts, instrumentalists, and office workers who don't have time for manicures.
