Staleks - Crescent Mineral Nail File SMART 40 150/180 grit (25 pcs)

Smart 40 Crescent Mineral Nail File (150/180 Grit)

A pairing that shifts the balance toward natural nail work — 150 grit for artificial nails and dense natural filing, 180 grit stepping in as the finer, more versatile side for shaping and prepping natural nails before coating.

What each grit does:

• 150 grit: medium hardness, suited to artificial nails and filing dense natural nails
• 180 grit: versatile, suited to natural nail work — shaping, light buffing, and prep before a coating goes on

Compared to 150/150's uniform feel, this pairing gives you a coarser option and a genuinely lighter-touch option on the same file, useful when a service moves between artificial and natural nail work in the same sitting.

The crescent shape keeps the same functional split as the rest of the line — 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: Is 180 grit gentle enough for natural nails? Yes — 180 is described as versatile for natural nail work specifically, including shaping, light buffing, and preparation before applying a coating.
