Nail Buffer is a handheld manicure tool used to smooth and shine nails for a polished, healthy appearance. It typically features multiple textured sides — from rough to fine grit — to file, buff, and polish the nail surface. By gently smoothing ridges and imperfections, a nail buffer helps create an even, glossy finish without polish. It also promotes better adhesion for nail polish and enhances overall nail health and appearance. Lightweight and easy to use, a nail buffer is an essential item for at-home nail care or professional manicures.
