Staleks Expert 40 Boomerang Nail File 100/150

The professional mineral nail file Staleks Expert 40 Boomerang (Grit 100/150) offers the ideal balance in a single professional-use tool, alternating between an intense abrasive side and a technical refining side.

Technology and Performance

This variant combines two complementary grits: the 100-grit side features a rigid texture for quick gel or acrylic removal and extension preparation, while the 150-grit side offers medium abrasiveness, perfect for structuring finer artificial nails or shaping exceptionally thick natural nails. Its ergonomic half-moon shape perfectly adapts to the anatomical contours of the nail, minimising the professional's physical effort. It also features a special anti-clogging coating that repels organic dust residue generated during use.
