Xinnun Nail Files Bulk 150 pcs 100/180 Grit Double-Sided Emery Boards — Sturdy Core, Rounded Edges

These disposable, double-sided emery boards combine a coarse 100-grit side for reducing length and reshaping with a finer 180-grit side for smoothing edges and refining the nail surface. The set includes 150 files sized about 7 x 1.1 x 0.16 inches with a sturdier core for comfortable handling. Rounded corners and wavy edges protect skin and cuticles while the PS glue board and emery paper construction resists bending and breakage during repeated use.

How do these files make shaping nails faster?

The 100-grit face removes bulk quickly—ideal for shortening acrylics, hard natural nails or shaping tips—while the 180-grit refines the contour without over-thinning. Using both sides in sequence saves time compared with single-grit files and reduces the need for multiple products.

• 100-grit removes length and reshapes hard nail material efficiently
• 180-grit smooths edges and refines the curve for an even finish
• Thicker board offers a firmer grip and more control during filing
• Large pack minimizes interruptions for replacements in busy sessions

Will these files protect my skin and cuticles while filing?

The edges are rounded and the sides have a gentle wave to prevent accidental scraping of surrounding skin. Their emery surface is securely bonded to the board, reducing loose particles and preventing rough edges that can irritate cuticles.

• Rounded corners lower the risk of nicks or snags
• Wavy edges add a buffer between the nail and skin
• Quality PS glue board keeps the abrasive layer intact
• Disposable design limits nail dust transfer and contamination

Can these files be used on acrylics, gels and natural nails?

Yes—the dual-grit design supports multiple nail materials. Use the coarse side for shaping and reducing artificial tips, then the finer grit to smooth and prepare the surface for polish or further enhancement. They are appropriate for acrylics, poly gels, dip powder systems and natural nails, though extremely rigid salon machines may outperform emery boards for heavy-duty removal.

• Suitable for acrylics, gel overlays, dip powder and natural nails
• Coarse grit for shaping; fine grit for smoothing and finishing
• Works for both manicures and pedicures
• Easy to rinse clean after light debris removal

How does the 150-piece quantity help salons and home users?

A 150-count supply reduces the need for frequent restocking and is convenient for multi-client appointments or extended at-home use. Having multiple files on hand also supports hygienic one-use practices and speeds up workflow during busy periods.

• Ample quantity for salons, beauty techs, and DIY enthusiasts
• Cost-effective for frequent replacements and single-use hygiene
• Uniform size fits most nail shapes and filing routines
• Compact packaging stores easily in kits or drawers
