I hate having to turn the nail polish remover bottle over onto a cotton ball simply for the fact that the ball gets saturated then I spell like acetone for a day regardless of the amount of time I spend washing my hands. I saw these in the store and I just had to try them and to my surprise they worked wonders. It took about two swipes to get the polish over. I didn't have to scrape at my nails over and over again until they were clear. I was beyond impressed with this, they also don't have such an over powerful smell to them.
