BTYMS 80/80 Grit Nail Files Review: Are They Worth It?
Introduction
The BTYMS 10 Count 80/80 Grit Rectangle Nail Files are coarse emery-board nail files for acrylic and other artificial nails. Their primary use is quickly reducing length, shaping sidewalls and free edges, and removing bulk from extensions or cured nail enhancements.
This BTYMS 80/80 grit nail file set is aimed at DIY users, nail enthusiasts, and manicure stations that need a dedicated heavy-shaping abrasive. It sits in the practical, consumable end of the category rather than the fine-finishing or premium reusable-file segment.
🏆 My Quick Verdict
💡 Best For: Acrylic, gel, polygel, tips, extensions, and other artificial-nail shaping where fast material removal matters.
⚡ Key Specs:
10 files; 80/80 grit; coarse grit type; rectangular profile; EVA material; blue; model Nail Files 80/80.
✅ Bottom Line: The defining advantage is fast, aggressive shaping on artificial nail material. The key trade-off is equally clear: both sides are 80 grit, so a finer file is still needed for delicate finishing.

Design & Build Quality
The BTYMS file uses a straight rectangular board with abrasive faces on both sides. The EVA-based construction gives the file a familiar emery-board format rather than the rigid feel of glass or metal.
The broad rectangular profile is practical for controlled strokes across acrylic length and sidewalls. Its biggest handling benefit is simplicity, because there is no special orientation or multi-stage surface to learn.
Both faces are 80 grit. That makes the board consistent from either side, but it also removes the option of switching to a gentler surface for finishing.
Expert Insight
An 80-grit file is best treated as a shaping tool, not a finishing tool. Use controlled pressure on artificial material, then change to a finer abrasive before refining the final edge.
Setup, Installation & Ease of Use
- Remove the files from their packaging and keep the boards flat between uses.
- Choose the 80-grit surface when you need fast reduction of artificial material.
- Use short, controlled strokes around sidewalls and the free edge.
- Reduce pressure as the desired length and shape are approached.
- Switch to a finer file before final smoothing or natural-nail finishing.
- Brush away filing dust after use and store the boards in a dry container.
Core Performance & Feature Breakdown
The core performance advantage is rapid material removal. BTYMS specifically positions the 80/80 boards for shortening acrylic nails, shaping sidewalls and free edges, and reducing gel or other enhancement material.
That coarse surface is useful when a finer board feels too slow on thick enhancements. It is also why the set should not be treated like a universal natural-nail file.
The double-sided design keeps the workflow predictable. You get the same abrasive level on each face, so flipping the file does not change the cutting intensity.
For buyers learning how grit affects filing speed and nail compatibility, NailPrime’s guide to nail-file differences provides useful context on abrasive levels and file types.
Key Features Explained
80/80 Coarse Grit
The 80/80 rating means both sides use the same coarse abrasive level. That matters most for acrylic, extensions, and other hard enhancement materials, but it is too aggressive for routine filing of fragile natural nails.
Double-Sided Emery Board
Both faces are usable, which keeps the tool straightforward during shaping sessions. The limitation is that neither side provides the finer 180- or 240-grit finish many users want at the end.
Rectangular Professional Shape
The straight rectangle provides a broad edge for length reduction and sidewall work. It is less specialized than curved or narrow files designed for intricate contouring.
Water-Resistant Positioning
BTYMS says the files are easy to clean and water resistant. That is convenient for routine maintenance, but water resistance should not be treated as a substitute for professional sanitation procedures.
Real-World Usability & Maintenance
The most practical way to use this set is as a dedicated coarse stage in a broader filing routine. It can remove bulk efficiently, while a separate finer file handles scratch reduction and final shaping.
Cleaning is relatively straightforward because the manufacturer describes the boards as water resistant and easy to clean. Even so, filing dust should be removed promptly, and professional users should follow the sanitation requirements that apply to disposable or reusable abrasive tools.
Storage matters because abrasive boards work best when the surfaces are kept clean and protected from unnecessary moisture. Replace a board when the abrasive becomes noticeably dull, uneven, or difficult to clean.
Premium Pros & Cons
Pros
- Fast 80-grit cutting is well matched to acrylic and enhancement shaping.
- Ten files provide useful spares for regular DIY use.
- Both sides use the same coarse grit for consistent handling.
- Rectangular boards offer a broad working edge for length and sidewall shaping.
Cons
- 80 grit is too aggressive for delicate natural-nail finishing.
- There is no finer abrasive side for final refinement.
- The set is specialized for shaping rather than complete manicure finishing.
Common Issues & Fixes
Too aggressive on natural nails
The coarse abrasive can remove natural-nail material faster than expected. Use a finer file for natural nails and reserve 80 grit for appropriate enhancement work.
Surface still feels rough after shaping
The 80-grit face is not intended to create a fine finish. Follow it with a 180- or 240-grit abrasive for smoother refinement.
File feels less effective over time
Abrasive surfaces naturally lose cutting ability with repeated use. Brush off dust, avoid unnecessary contamination, and replace the board when the grit becomes dull or uneven.
What to Know Before You Buy
The main compatibility check is nail material, not simply nail length. This set makes the most sense for acrylics, extensions, tips, gel or polygel shaping, and other applications where aggressive material removal is useful.
Do not choose it solely because an 80-grit file sounds professional. If your routine is mainly thin natural nails, edge maintenance, or polishing, a finer grit will give you more control.
Also note that the Amazon listing offers multiple grit and quantity variations under the same product family. Confirm that the selected option is the 80/80 grit, 10-count configuration before ordering.
Who Should Buy It / Who Should Skip It
✅ Who Should Buy It
- DIY users who regularly shape acrylic or other artificial enhancements.
- Nail enthusiasts who want a dedicated coarse shaping file.
- Users who prefer multiple inexpensive emery boards rather than one premium file.
- Manicure stations that already keep finer files for finishing.
✗ Who Should Skip It
- Users who mainly maintain thin or fragile natural nails.
- Anyone wanting one file that handles shaping and fine finishing.
- Buyers specifically seeking glass, crystal, or metal nail files.
- Users who need a complete polishing system in one package.

Check Price on AmazonIs It Worth It?
The BTYMS set is worth considering when your main need is fast, coarse shaping rather than a universal nail-care tool. Its strongest value comes from matching an aggressive abrasive to artificial material instead of asking one file to perform every stage.
The trade-off is the extra tool you will still need for refinement. Buyers who already own a finer file can use this set as a dedicated bulk-removal stage without paying for grit levels they may not need.
Final Verdict
The BTYMS 10 Count 80/80 Grit Rectangle Nail Files are a focused choice for fast acrylic and artificial-nail shaping. Their 80/80 construction is the main reason to buy them, while the lack of a finer side is the main reason to pair them with another file.
Frequently Asked Questions
Are these nail files suitable for natural nails?
They are better suited to artificial nails than delicate natural nails. The 80-grit surface is aggressive, so a finer file is generally easier to control on thin or fragile natural nails.
What nail materials are they designed for?
They are primarily designed for acrylic and other artificial nail materials. The listing specifically describes use for acrylic, gel extensions, fake nails, poly extension gel, and related shaping work.
What size are the individual files?
The listing does not clearly state the dimensions of each individual file. It lists product dimensions of 7 x 0.98 x 7 inches, so those figures should not be assumed to represent one board.
Can the files be cleaned?
BTYMS describes them as easy to clean and water resistant. For professional use, follow applicable sanitation procedures rather than relying on the water-resistant claim alone.
Do they include a warranty?
No manufacturer warranty is specified in the current product details. Amazon currently shows a 30-day refund or replacement policy for the listing, subject to its return terms.
Do I need another file after using 80/80 grit?
Yes, a finer file is recommended for smoother refinement. A 180- or 240-grit abrasive can reduce the deeper scratches left by an 80-grit shaping stage.
