Files, Buffers, Blocks
The Edge Nail Files and Buffers.
You probably will be very aware that all nail files and buffers are not the same. Files are made of tiny particles of grit which vary from being very coarse to medium - coarse to very fine.
Files are graded and numbered according to how many particles of grit per square inch, for example .
A very coarse file would be an 80 grit which means that there are 80 particles of grit per square inch.
A medium coarse file would be a 100 grit file which means there are 180 particles of grit per square inch.
A much less abrasive or very fine file would be 240 grit having 240 particles or grit per square inch.
So remember, the higher the number, the more particles of grit per square inch and the finer the file. Buffers are also made from tiny particles of grit but are much less abrasive and help smooth nail ridges, giving a high gloss to the nail.
Buffers can be anything from 1200 grit upwards.
