BTYMS 50 Count Rectangle Nail Files 80/80 Grit Coarse Emery Boards — Reusable Water-Resistant

BTYMS 50 Count rectangle 80/80 grit nail files are coarse, durable emery boards designed to quickly shorten, shape, and refine acrylic, gel, and extension nails.

These heavy-duty rectangle nail files from BTYMS are made with quality adhesive tape and emery materials to withstand repeated use while staying water resistant and easy to clean. The 80/80 grit is intentionally coarse to remove length, smooth sidewalls, and reduce gel overlays efficiently. Supplied in a bulk 50-count pack, they’re tailored for busy salons, nail techs, and at-home enthusiasts who need consistent, strong filing power without frequent replacements.

How do these 80 grit files perform on acrylic and extended nails?

The 80/80 grit surface is coarse enough to quickly take down acrylic length and thin extended overlays without bogging down. You'll get fast, controlled removal while keeping a predictable shape of the free edge.

• Fast reduction of length on acrylic and hard gels.
• Effective at shaping side walls and the free edge.
• Symmetrical 80/80 grit on both sides for longer usable life.

Are these emery boards reusable and easy to maintain?

Yes — BTYMS files use durable adhesive and emery layers that resist water and debris, so they hold up through multiple uses and cleanings. Wiping or rinsing under water removes residue; allow to dry thoroughly before storing to keep the grit intact.

• Water-resistant construction eases cleanup.
• Wipe or rinse to remove dust and product residue.
• Durable adhesive backing reduces grain loss over time.

What makes the rectangle shape useful compared to other file shapes?

The straight rectangle profile provides broad, predictable contact with the nail for even filing and consistent shaping. It’s especially handy for technicians working quickly or anyone creating square or squoval tips where edge consistency matters.

• Wide surface for rapid material removal.
• Flat edges help define square and squoval shapes precisely.
• Easy to hold and control during repetitive salon work.

Can these files be used for anything besides salon nails?

Beyond acrylic and gel nails, the coarse emery is suitable for prepping and smoothing many artificial surfaces and even light pet grooming tasks where a robust grit is needed. Use with care — 80 grit is aggressive and meant for non-delicate surfaces.

• Works on poly extensions, hard gels, and artificial tips.
• Useful for smoothing small hard surfaces in craft or hobby projects.
• Occasional use in pet grooming for trimming hard keratin areas, with caution.

Who is this for: Nail technicians, busy salons, and DIY nail fans who need a bulk supply of dependable, coarse files for acrylics and extensions. If you work with hard gels, need quick length reduction, or prefer a consistent rectangle profile for shaping, this 50-count BTYMS pack offers rugged performance and easy maintenance without frequent replacements.
