STALEKS PRO EXPERT 40 – 150/180 grit (25 pcs)
The Tool
The EXPERT 40 crescent-shaped mineral nail file is a professional tool with dual grit surfaces (150 grit and 180 grit) designed for both shaping artificial nails and refining natural nails. Comes in a pack of 25 single-use files.

With its half-moon shape and flexible plastic base, it offers precision for both curved motion and straight edges. The surface with 150 grit is ideal for shaping and thickness correction; the 180 grit side handles both artificial and natural nails. The special coating prevents clogging by organic dust. A thin foam layer reduces pressure on the nail plate for increased comfort.
