Staleks - Crescent Mineral Nail File SMART 40 100/100 grit (25 pcs)

Smart 40 Crescent Mineral Nail File (100/100 Grit)

A step up from the coarsest 80-grit option — 100 grit on both working surfaces, built for artificial nail work that needs a hard abrasive without going as aggressive as the roughest grade in the line.

Two Sides, Two Jobs

• Straight side: filing length and creating a precise, defined shape
• Curved side: working in the cuticle area and along the lateral nail folds

Why 100 Grit

100 grit is a hard abrasive used for filing artificial nails, correcting their shape, and removing length — it can also prep the surface before an extension, sitting between the aggressive 80 grit and the finer grades used for lighter finishing work.

Build Quality

• Stearate coating prevents the abrasive from clogging with organic dust during use
• Thin foam layer reduces pressure on the nail plate during filing
• High-quality abrasive holds its cutting properties over extended use
• Versatile for both natural and artificial nail work

FAQ

When should I reach for 100/100 instead of 80/80?
100 grit still handles artificial nail correction and shape work, but with less aggressive removal than 80 grit — a better fit once you're past heavy material removal and into shaping or surface prep.
