OPI Crystal File

This file is the only file I ever use on my nails, it’s the best I've ever tried. It seals the free edge and stops my nails from splitting (which they are very prone to do) and it so easy to control to shape your nails too. You have to be quite gentle with it but it will repay you in lovely strong nails.

To find out what shape is best for your nails just look at your cuticles, technically you should mirror them. I say technically because I don't. Just experiment and find a shape that you like!

OPI claim the file won't wear out, so I don't really mind the price.
I found mine on Ebay for about £8.

It’s a 240 grit file, which I find is a good all round for filing down and shaping.
The higher the grit number, the softer the file is. This is a 'medium' file. The lower the grit number the more coarse the file.
