Staleks - Crescent Mineral Nail File SMART 40 150/240 grit (25 pcs)

Smart 40 Crescent Mineral Nail File (150/240 Grit)

The widest spread between two grits in the Smart 40 range so far — 150 for artificial nail work and dense natural filing, 240 for the fine, finishing-stage work that comes right before a coating goes on.

What each grit does:

• 150 grit: medium hardness, suited to artificial nails and filing dense natural nails
• 240 grit: fine abrasive, for grinding and filing both natural and artificial nails, and preparing the surface for coating

That gap between the two sides makes this file a genuine two-stage tool — start with 150 for shaping or correction, then flip to 240 for the smooth, ready-for-polish finish, rather than reaching for a separate finer file.

The crescent shape still splits by function — straight side for length and shape, curved side for cuticle-area and lateral fold work.

Shared build quality across Smart 40:

• Stearate coating prevents clogging from organic dust
• Thin foam layer reduces pressure on the nail plate
• High-quality abrasive holds its properties over extended use

FAQ: Can I use the 240 side to prep for coating without switching files? Yes — 240 grit is specifically suited to grinding and filing before applying a coating, so this file can take you from shaping through to pre-polish prep on its own.
