What is a "nail brush"?

A nail brush is a small handheld tool with bristles used for cleaning and scrubbing nails and cuticles. Typically, it features a compact rectangular or oval shape with dense bristles on one side. The bristles are firm yet gentle, designed to effectively remove dirt, debris, and residue from the nails and cuticles. By applying soap or a cleansing solution and gently scrubbing the nails, the nail brush helps to maintain cleanliness and hygiene. It is commonly used during manicures and pedicures to prep the nails before applying nail polish or treatments.
