What is the primary purpose of a nail buffer?

The primary purpose of a nail buffer is to give nails a shiny finish. Buffers are designed to polish the nail surface, which enhances its natural shine. This process involves using a buffer block that has a fine abrasive surface to smooth out any irregularities on the nail, resulting in a polished and glossy appearance. Additionally, a shiny finish can create an appealing look, which is often desired by clients after a manicure or nail care service.

While buffers can contribute to smoothing out the nail's surface, their main function emphasizes improving the shine rather than shaping or cutting the nails. Other options, such as shortening or removing stains, are tasks best suited for different tools and techniques rather than a nail buffer.
