I recently purchased a glass dry erase board. The magnets I had on my previous one didn't work with my new glass. So I bought these. To my surprise, the magnets actually stuck to the board with no problem! Not only did they stick, they held the 4 sheets of paper in place and still seemed to be in place. Although I haven't tried it, I'm sure it can last longer. I also find magnets very attractive.
