I have done my own nails for years and have always used a buffer after filing to smooth out rough edges and ridges. This is the best one I have found. And it lasts. And lasts.

love it!!!

This Buffer is the best one I have come across in a while. It's comfortable to use and does a great job..

I absolutely adore this buffer! After searching for the perfect buffer, I finally found this a couple years ago. They are perfect, I haven’t bought a different brand since. This buffer has super high grits on both sides, which makes it perfect for smoothing the nail & prepping it for polish without damage! I make sure I always have at least two, one I’m using & a backup. Another benefit of this buffer is that it lasts forever. I usually lose it before it loses its grit. I’ll never use another brand!!!

Love how smooth my nails are for polish application. Great for days you let your nails breathe, too.
