I bought one many years ago from a Stand that was in the lowry outlet which came with a lovely nail gel to give that extra shine but then I either finished or misplaced it so now I buy the superdrug 4 way buffer block and My nails have come out lovely and shiny smooth after using this. It makes polish application look even prettier. Nails even looks nice left on their own if you have nails strong enough and a job that doesnt demand sacrifices to the nail gods every other day like mine. Ive had several uses out of it and its still working fine.
@Ashli ta...I used to buy the nail buffers from the body shop but that must have been over 10 years ago. Luckily my nails are strong and my job involves tapping away on a keyboard so minimum impact on the nails.
