To clarify about the rating, the nail polish I ordered came with a "stuck" brush - which I thought was random and a problem with the brush itself, so I simply replaced it with another one from a different nail polish that had run out. However, after 1-2 days, the new brush experienced the exact same issue - in other words, the nail polish was what was "sticking" to the brushes. I contacted the store and they immediately replaced it for me, and the new one is fine. I am not a professional and I have no idea why or if this happens frequently, so if anyone knows or has a similar experience, I would like to know!
