A nail buffer is a grooming tool used to smooth and shine the nails. It typically consists of a small block of abrasive material, such as fine grit sandpaper, with different surfaces for buffing and polishing the nails.
A 7-in-1 nail buffer solution may include several different surfaces on the buffer block for different nail care tasks, such as shaping the nails, removing ridges, buffing the surface of the nails to a shine, and polishing the nails to a high gloss. The buffer may also include a cuticle pusher and other tools for maintaining the nails and cuticles.
The color of the buffer block may vary and is usually chosen at random. It is not typically a factor in the performance of the buffer.
