Staleks Expert 40 100/180 Crescent Mineral Nail File - 25 Pcs

The Staleks Expert 40 Crescent Mineral Nail File delivers repeatable, salon-grade shaping through a dual-grit mineral substrate engineered for continuous handpiece and manual use. Rather than depending on standard abrasive coatings that shed prematurely, each tool merges two distinct roughness levels into a single curved body, providing dependable cutting action from initial bulk reduction to final edge refinement.

Dual-Grit Progression for Natural and Artificial Nails

The 100-grit face clears length and softens thick plates efficiently, while also cutting through acrylic, gel, and dip resin structures. Rotate to the 180-grit side to feather free-edge burrs, clean up sidewalls, and smooth surface texture before applying overlays. The fixed transition between both sides prevents the uneven filing patterns that often occur when switching disposable tools mid-service.

Crescent Profile for Stable Grip and Lateral Control

Molded to trace the fingertip curve, this shape keeps the abrasive track aligned with the nail plate edge without digging into adjacent skin. The ergonomic contour spreads pressure across the thumb and forefinger, reducing tension during extended manicure sessions. A specialized surface finish improves traction under light moisture and resists particle adhesion, keeping the working area clear between wipes.

Heavy-Duty Mineral Build for Continuous Workflow

• 25-count packing supports consistent station stocking, technician rotation, and client-takeaway retail formats.
• Mineral construction withstands routine sanitization without fracturing or losing abrasiveness.
• Dual roughness eliminates guesswork, delivering predictable material removal rates across diverse nail types.

Whether you are managing a high-volume appointment calendar or maintaining a home kit, these files provide reliable geometry and cutting consistency that simplifies prep workflows and extends service throughput.
