Precision-engineered square nail files with dual-grit technology combining 80 and 100 grits for versatile shaping and finishing. The 80 grit efficiently removes length and reshapes nail edges, while the 100 grit delivers a smooth, refined finish ready for polish application. The square profile provides excellent control for creating defined corners and straight edges. Ideal for both natural and artificial nails, these files minimise splitting and peeling when used with proper technique. Essential tools for professional nail technicians and home users seeking salon-quality results.
