Why Choose This Professional Nail File?

A reliable professional nail file is essential when technicians need to reduce bulk, refine shape or prepare an existing enhancement for rebalancing. The 150/150 grit provides medium filing action without moving into the heavier cutting action of a coarse file.

The Endurance construction is also designed for extended use. According to NSI, these files last around four times longer than an average abrasive, helping reduce how frequently technicians need to replace their professional files.

Product Reduction and Rebalancing

The Endurance Nail File 150 is particularly useful when reducing enhancement product before a rebalance or refinement service. Its medium grit helps remove product efficiently while allowing the technician to maintain control over the final shape.

Use light, even filing strokes and regularly check the enhancement to avoid removing more product than required.

Straight Edge for Sidewalls and Extensions

The straight edge is designed for refining sidewalls and extension edges. This makes the 150 grit nail file useful when creating clean lines and maintaining a balanced enhancement shape.

Accurate sidewall refinement can help improve the appearance of square, almond, coffin and other professional nail shapes.

Contoured Edge for Detailed Filing

The curved bridge side helps technicians work closer to the cuticle and sidewall areas while reducing the risk of unnecessarily touching surrounding soft tissue.

This shape gives the medium grit nail file additional versatility compared with a completely straight file and can make detailed refinement easier during professional enhancement services.

Suitable for Multiple Nail Systems

NSI Endurance files can be incorporated into a range of professional nail services, including acrylic, gel and wrap enhancement systems. The 150/150 medium grit is particularly useful where controlled product reduction and reshaping are required.

NSI recommends a 180 grit file as the preferred option for natural nails. If a 150 grit file is used on a natural nail, extremely light pressure should be used to avoid excessive filing or thinning.

How to Use the Endurance Nail File 150

Use the Endurance Nail File 150 with controlled, even strokes over the enhancement surface. Begin by reducing unwanted bulk, then refine the sidewalls, free edge and overall shape as required.

Use the straight edge for extension and sidewall refinement. The contoured edge can be used for greater control in areas closer to the cuticle and surrounding skin.

Always file with appropriate pressure and technique for the enhancement system being serviced.

Professional Hygiene and File Care

NSI states that Endurance files can be disinfected using complete submersion for approximately 10 minutes or by spraying with an appropriate hospital-grade disinfectant according to the disinfectant manufacturer’s directions.

Follow your salon hygiene procedures and relevant local requirements for cleaning, disinfection and replacement of reusable nail files between clients.

Built for Busy Nail Technicians

The combination of durable abrasive material, medium filing action and versatile edge design makes this professional nail file useful for technicians performing regular enhancement services.

For product reduction, rebalancing and reshaping, the Endurance Nail File 150 provides reliable control while helping reduce the effort required during routine professional filing.
