Manicure sanding bands are small cylindrical tools used in nail care, typically with an electric nail file or drill. They are designed for smoothing, shaping, and buffing nails, as well as for removing gel polish or acrylics. The bands are made of an abrasive material, often coated with sand or grit, which helps to file down the nail surface effectively. They come in various grits, allowing for different levels of abrasion depending on the specific nail treatment being performed.
