Frequently Asked Questions

Q: What is the difference between the 100, 150, 180, and 240 grit nail files?

A: Grit refers to the coarseness of the abrasive surface. 100 grit is the coarsest and is ideal for shaping and shortening natural nails quickly. 150 grit is medium-coarse, great for initial shaping with more control. 180 grit is fine and used for smoothing and refining nail edges. 240 grit is the finest and is perfect for gentle buffing and creating a smooth, shiny finish before or without nail polish.

Q: Are these nail files safe to use on natural nails?

A: Yes! These dual-sided nail files are specifically designed for natural nails. The range of grits (100–240) allows you to progress from shaping to smoothing to buffing gently without over-filing or damaging the nail plate. Always file in one direction for the healthiest results.

Q: What is the scale line and reference graphic used for?

A: The scale line and reference graphic printed on the nail file help you measure nail length and maintain a consistent filing angle. This makes it easier to achieve symmetrical nail shapes — ideal for beginners who want professional-looking results without guesswork.

Q: How many nail files come in the package?

A: Each listing includes one unit (one dual-sided nail file). Since both sides are active filing surfaces, you get two working grits per file. Check the selected variant for your preferred grit combination.
