Best nail polish remover EVER.  Used by my favorite nail tech at a nearby salon, I find this to remove even the most stubborn polish without smearing it all over my fingers.  Soak a tiny piece of cotton ball and place on each nail.  By the time you've got the 10th finger covered, it's time to take a full size cotton ball, wet it with the remover and take the polish off in a few easy swipes.  No drying or ashy look to nails.
