These last forever!  I still have ones I bought years ago.  I have long thick hair, they hold great.  Love them! [SEP] I have been looking for these for years.  I still have a few of the ones I bought years and years ago, but haven't been able to find them.  I just figured they were a relic of the past, and then I stumbled across them on Amazon.  I keep one in the shower, so after conditioning I can put my hair up while the conditioner does its thing.  I keep a few with my other hair products, in case I want to clip it in place till the gel or whatever product of the moment kicks in.  I keep a couple around for working out, to get my hair out of the way.  I keep a couple by my bedside, in case it's a warm night and I want it up.  These are so incredibly handy.  I love them, they work great.  The only way I've had them break is if someone steps on them!  They won't just crack or snap or anything.  I bought two packs of them, so that should last me a lifetime!
