I wanted earrings that I could leave in all day and all night. I found them!  Look at the guarantees. I have a nickel allergy and often when I'd wake up I'd be missing an earring. These are guaranteed hypo-allergenic and not to come out.

Someone's review said they were too short. They're 1 1/2". That's not at all short. I think they're just the right length.

The instructions on how to put them on are on the flyer page that you get with the earrings. It make take a little time to get them on and off the first time. But I had no problems after that.
