I bought #81, #82, and #83 a little over a year ago and they had been sitting for almost a year. When I went to go see if they were ok last week, the DACP and Hand Polish was fine (still creamy) but the Swirl Free Polish was really wattery. I shook up the bottle and a few minutes but that didnt change the consistancy. So...just wondering what the shelf life was if anyone has had it for that long.
