I have been buying various gel polishes over time to build up my colors for my clients. Today I had to throw away 9 bottles of gelish polishes because they were sticky, gummy, and the brushes were ruined. I know the lids were on tight because I had to twist harder than usual to open them. They aren't any older than the other brands I have in my collection & gelish is the only brand out of 200+ bottles that have done this which leads me to believe it's definitely the brand. That's an estimated $150 I now have to replace & will obviously not be buying gelish to do so.
