Nail buffers are essential tools for creating a smooth, polished finish on nails. They are designed to refine and shine the nail surface, and the numbers on them indicate their level of abrasiveness. The higher the number, the softer the file, and the lower the number, the sharper the file. For example, a 100/180 grit buffer is used to even out ridges and smooth rough patches on acrylic or gel nails.

| Level of abrasiveness | Higher number = smoother/finer |
| Lower number = sharper | |
| Grit | Higher number = softer |

The numbers indicate the level of abrasiveness of the buffer
The numbers on nail buffers indicate the level of abrasiveness of the buffer. The higher the number, the smoother and finer the buffer will be. For example, a number of 240 or above will be suitable for natural nails. A lower number means a sharper file. The sharpest file on the market is 80/80 grit, which is used for product removal. The numbers refer to the size of each grain, or how many grains of sand fit into one square inch.

Higher numbers mean a smoother/finer buffer
Nail buffers are tools used to create a smooth, polished finish on nails. They are designed to refine and shine the nail surface. Buffers have grit numbers, which indicate their level of abrasiveness. The higher the number, the softer the buffer, and the smoother the finish.
Buffers with a higher grit number are ideal for creating a smooth base for the next buffing stages. For example, a 100/180 grit buffer is used to even out ridges and smooth rough patches on acrylic or gel nails. The 100 grit side is used first, followed by the 180 grit side to further refine the nail surface.
Nail files and buffers both have numbers that indicate the level of coarseness or grit. The numbers refer to the size of each grain of sand on the surface, with smaller grains resulting in a smoother finish. For example, a 240 grit buffer is used to prep nails before UV gel polish application due to its low corrosive surface.
It is important to note that buffers are made with a sponge, making them softer and more delicate than hard nail files. While nail files are primarily used for shaping and reducing length, buffers are specifically designed to shine and refine the nail surface.

The numbers refer to the size of each grain
The numbers on nail buffers refer to the size of each grain. The higher the number, the more grains of sand fit into one square inch, and the softer the file. A higher number (240+) means the file will be smoother and finer.
Buffers with a lower number are sharper. An 80 grit file, for example, is used for product removal as it allows you to file off a lot of product quickly. However, you should never over-file the nail, so don't use an 80 grit file when the product is very thin.
If a nail buffer has two different numbers, this means that it has two different sides with different levels of coarseness. If both numbers are the same, then both sides have the same grit.

The numbers indicate the grit of the buffer
The numbers on nail buffers indicate the grit of the buffer, or in other words, the level of abrasiveness. The higher the number, the softer the file, and the lower the number, the sharper the file. For example, a buffer with a number of 240 or higher will be smoother and finer. The numbers refer to the size of each grain, or how many grains of sand fit into one square inch.
