OPI Edge Nail File

A 150-grit file is considered medium-coarse. It is designed for shaping and refining the edges of artificial nail enhancements or for quickly shortening the length of thicker, natural nails.

While it can be used on natural nails, 150 grit is relatively coarse. It is best suited for shaping sturdy nails or removing length quickly; for finishing or smoothing delicate natural nails, you may prefer a higher grit file.

The cushioned core provides a slight amount of flexibility, which helps prevent you from applying too much pressure while filing. This design makes it easier to control the file and reduces the risk of damaging the nail plate.

These files are designed for professional, single-client use. While they are durable, they are typically intended to be discarded after the service to maintain hygiene standards in a salon environment.

Professional-grade tools like this are optimized for the speed and precision required in a salon setting. While anyone can use them, the grit and construction are specifically calibrated for technicians who understand how to safely shape nails without causing thinning or trauma.
