Files and buffers with a grit of 150 to 180 are typically used for what purpose?

Files and buffers with a grit of 150 to 180 are specifically designed for smoothing and refining the surfaces of the nails. This grit range allows for the effective reduction of surface irregularities while being gentle enough to avoid damaging the nail. The smoothing achieved with this grit is essential in preparing the nail for further services, such as polishing or applying nail enhancements.

In contrast, lower grit files, which are more abrasive, are typically used for more aggressive shaping or removal of products, while higher grit buffers are meant for polishing to a shine. Therefore, a grit rating of 150 to 180 particularly serves the purpose of creating a more refined finish on the nail, making it suitable for this task.
