The paper is thin - I doubted they could hold a decent magnetic curtain rod. You had no problem! One problem - common to all 3m products - "sticky" is not sticky enough. All of their products are like that though, so that's to be expected. They fell several times because the glue was weak. I added a drop of super glue to each of them and it worked perfectly. Would give it 4 stars for that - but they are SUPER light and thin and easy to work with and there are 2 sizes in the pack - I would buy them again so I'm giving them 5 stars.
