I have to say that we had a bottle of nail polish that has been stuck closed for almost a year. I tried everything and could not get the thing open so I pretty much had given up. Then I saw this Pin and I thought I would try it. Not only did it work but it worked FAST!!! I put the bottle in and within a few seconds I was able to open the bottle. Not only was it fast and it worked but it was cheap. A glass and water, that is all you need. I was so happy, it is one of my favorite colors and has quite a bit left in the bottle. YAY!! for pins that work. I absolutely love it when they turn out.
