Q: Is the Endurance 150/150 file suitable for use on the natural nail?
A: No. The Endurance 150/150 file when used on the natural nail will damage and weaken the nail plate, which is the foundation for any nail enhancement. The lower the number the more abrasive the file will be. A 180-grit file or higher is suitable for use on the natural nail.
