Finally, the file without the annoying shopping centre sales kiosk! Yep, the one with all those pushy sales people. Most people who have been pressured into buying the shopping centre pack know that the 4 way buffer is by far the best part of the kit. It gives your nails a lovely shine, just like you are wearing polish. This is the best and quickest way to take care of your nails, and is fantastic if you are a lazy groomer.
