Staleks - Crescent Mineral Nail File SMART 40 100/150 grit (25 pcs)

Smart 40 Crescent Mineral Nail File (100/150 Grit)

Two grits built for the same job at different stages — 100 for correcting shape and removing length, 150 for the follow-up work on artificial nails or dense natural ones.

The straight side handles length and shape; the curved side takes on cuticle-area work and the lateral folds — same crescent design across the whole Smart 40 line.

What each grit is actually for:

• 100 grit: hard abrasive, used for filing artificial nails, correcting shape, removing length, prepping the surface before an extension
• 150 grit: medium hardness, suited to artificial nails and filing dense natural nails

Why the coating matters: a stearate finish keeps the abrasive from clogging with organic dust mid-service, and a thin foam layer takes some of the pressure off the nail plate as you work — small details that add up over a full day of filing.

Suited to both natural and artificial nail work — a versatile combination rather than a specialist single-grit file.

FAQ: What's the practical difference between using 100 and 150 grit on the same file? 100 grit handles the heavier shape correction and length removal, while 150 grit steps in for finer filing on artificial nails or thicker natural ones — moving from one side to the other covers both stages without switching tools.
