No more messing around with acetone, just rip the wrap open following the marked line and put your finger in the pouch. Turn the edges tightly around the finger as if you were making a package and let sit for approx. 10min.
Remove the wrap while pulling off the old polish and finish it off by cleaning the nail with some nail polish remover. All done! How convenient.
Ps. Remember to first break the surface layer of your gel polish with a buffer file.
