Foot callus remover

called a foot file

It is a foot callus remover.

Because I wear slippers a lot in the summer

Foot care is important, and it is good to use when your heels are cracked or have calluses.

It doesn't look very aesthetically pleasing anyway.

If you rub with the rough side first, it removes dead skin cells to some extent, and then the slightly softer

If you finish it off the back part, it will be a temporary measure

It's fine for a week or two.

It might vary from person to person, but if you do it too hard

You should use it in moderation as you could get hurt.
