I really like these nail files for both professional and personal use. The 180/180 grit is perfect for shaping natural nails as well as refining gel and acrylic edges. They are strong, durable, and don’t wear out quickly like cheaper files. I also love that they are washable, which makes them more hygienic and long-lasting. Buying them in a 50 pack is great value for money and super convenient for a salon setting.
