4-in-1 Nail Buffer Fine Polishing Block

This nail buffer block is sized at 11.5 cm × 2.5 cm × 1.2 cm and weighs only 25 g, making it highly portable without compromising rigidity. Its four-sided design uses graded abrasive composites — each side calibrated for a specific stage of nail refinement: initial shaping, surface levelling, dead-cell removal, and final gloss enhancement. The material blend balances flexibility and firmness to conform slightly under fingertip pressure while delivering even contact across the nail plate. Tested for safety on delicate periungual tissue, it’s appropriate for regular use by teens, adults, and older users seeking low-effort, high-control nail maintenance.
