I bought these two years ago and I still only ever wear these. The back screws on so virtually no way for them to fall off or poke, and you can keep them in as long as you want. I wear them at night, swimming, all the time. They're stainless steel so no green marks or anything from cheap earrings, $11 for 5 pairs. Probably one of the best and most useful and worthwhile purchases I've ever made.
