Does anyone else remember the days of little bits of wire with plastic or paper round them that you twisted and twisted to close a bag? Yes. Well so do I. And I'd never go back to it. One of these on practically any size bag and job done. I've just bought my second set. The first set are still going, after a number of years, but I'm using so many of them that I was getting low. I've never even had one break yet despite putting them in the dishwasher whenever I've finished with one. Freezer bags, food storage bags, pasta bags, rice bags, breakfast cereal bags, bags with your toiletries in to go in your suitcase etc, etc. I once bought a set from a well known door to door catalogue. Theirs broke after a couple of uses.
