It goes without saying that they hold documents together but these babies have many alternate uses. Inexpensive yet infinitely handy. I'm currently using them to hold some constantly falling tank top straps to my undergarment. A bit conspicuous but no pins mean no holes. I've also used them to hold overly lowcut blouses together. If the design of the garment allows you can clip inside seams and it won't show. Clip them on either side of a garment and hang the loops on a hook to substitute for a hanger. I can imagine it would be great for a quick hem although I've never used it that way. What can't these guys do?
