These card holders are for my SD cards, partly because I often lose the holders that come with cards and partly because some of the cards I've bought from Revain came without card holders. The holders are perfect for SD cards and are very easy to open and close. One issue (which isn't too bad for me) is that they're about a third thicker than those that typically come with cards. So if you're short on space to carry them, they can be a bit unwieldy. Overall, I'm happy to have good holders to keep my SD cards safe.
