This is the Stylfile by Tom Pellereau.
I have never seen one like this before so was intrigued and had to buy it. It was only about £3.
It is curved to apparently make it easier to file your nails. It is not just a file but also a buffer and has 4 steps to using it which are shown on the back of the packaging.
I did find the file a little easier to use as my nails are quite curved so it seemed less vigorous when filing.
It was also quite fun to use :)
Has anyone else tried this file or one similar?
I would love to know your thoughts on it :)
Thanks for reading!
