I always try to remember to wipe down my bottles after using them or at least every so often. Today I went to open my O.P.I. Ridge Filler since my nails have been a peeling mess lately and low and behold it's sealed shut. I asked my dad and even he couldn't open it. After awhile of trying he broke out the rubber cord and then the pliers. This was the outcome. Barely used enough to have a proper burial.
