Professional Nail File & Buffer Collection

Level up your prep and finishing with salon-grade, black, double-sided files in three tuned grit pairings, 100/150, 100/180, and 180/240. Available in 5-packs and 10-packs for easy restocks. Each pairing is chosen to cover the complete service flow: controlled bulk-reduction on enhancements, precise refining, and gentle finishing for natural nails.

Why grit choice matters?

Across top professional guides and retailers, the consistent advice is: lower numbers = coarser (faster removal) and higher numbers = finer (gentler finishing). Choosing correctly prevents unnecessary heat, scratching and over-filing, particularly on natural nails.

The three grit pairings:

• 100/150: Built for product reduction and pre-shape on acrylic, hard gel or BIAB overlays. The 100 side powers through bulk; the 150 side refines before finishing. Not recommended directly on thin natural nails due to the coarser cut. 
  
  

• 100/180: A versatile workhorse for shaping enhancements and smoothing edges prior to top-coat steps. Ideal when you want one tool that moves from controlled reduction to a smoother refine without switching grits constantly. Industry recommendations frequently position 180 as a safe general-use grit for shaping product.
  
  

• 180/240: Gentle finishing and natural-nail prep. Use 180 to softly refine gels/BIAB, then 240 for delicate edge work and pre-polish prep.

Build quality you can feel

• Double-sided abrasives for fewer tool swaps mid-service and consistent bite from first client to last.
  
  

• Black pro finish that hides wear and resists looking “dusty” between clients, maintaining a clean, professional station aesthetic.
  
  

• Half-moon profile supports clean work around sidewalls and near the cuticle line, useful during refine/finish phases.

Pro tips for efficient, safer filing

• Pressure & passes: Let the grit do the work; heavy pressure increases heat and scratching.
  
  

• Sequence: Reduce with the lower grit, finish on the higher grit to minimise visible scratch lines under top coat.
  
  

• Natural nails: Stay in the 180-240 band to avoid splitting and thinning.

Suggested use-cases

• Acrylic/Hard Gel/BIAB debulk: Start 100/150 (100 side), refine 150 or 180, finish 240 if needed.
  
  

• Gel polish overlays: Shape with 180, refine/edge with 240 to reduce micro-scratches before top coat.
  
  

• Natural nail prep: Limit to 180/240 for gentle shaping and pre-polish smoothing.

Frequently Asked Questions (FAQ)

Q: What is a file used for?

A: They are essential for shaping, shortening, and smoothing the edges of your nails. They help refine your nail shape, prep for polish, and remove excess product from enhancements like acrylic, gel, or BIAB nails.

Q: What type should I use?

A: The best type depends on your nail type and the task at hand. Coarser files (like 100/180 grit) are great for filing acrylics or gels, while finer files (like 180/240 grit) are better for shaping natural nails without causing damage.

Q: How do I choose the right grit for my nails?

A:

• 100/180 grit – Best for shaping acrylic and thick enhancements
  
  

• 100/150 grit – Ideal for smoothing and shaping hard gel or BIAB
  
  

• 180/240 grit – Perfect for gentle shaping and finishing natural nails

Use coarser grits for product removal or shaping, and finer grits for refining and finishing.

Q: What grit is best for natural nails?

A: For natural nails, always use a 180/240 grit file. It’s gentle enough to shape without splitting or damaging the nail plate and provides a smooth, polished edge.

Q: How should I file my nails properly?

A: Always file in one direction (not back and forth), using gentle strokes to avoid splitting. Start at the side edge and shape toward the centre. For natural nails, avoid over-filing and use a fine-grit file like 180/240 for the best results.

Q: Can I use the same grit on acrylic and natural nails?

A: It’s best to use different grit levels for different materials. Acrylics need coarser files like 100/180 grit, while natural nails require a finer grit to prevent damage. Using one file for both can wear it out faster and risk harming your natural nails.

Q: How long do they last?

A: That depends on how often you use them and the type of nails you’re filing. Belle Beauty’s nail files are salon-tested for durability and long-lasting grit. Clean and store them properly to maximise their lifespan.

Q: Are they suitable for beginners?

A: Yes! Our files are easy to use, comfortable to hold, and available in grit levels suitable for every skill level—from at-home users to professional nail techs.
