Clip for attaching to a pair of disposable chopsticks so they can be used to close plastic or paper bags. It may need to be glued in place depending on the fit.
Slide the chopsticks over the side of the bag (one on each side), roll the top of the bag, then slide it in further, using the printed hook to keep it from unrolling. I've been mostly using these for larger bags (rice, flour, etc).
