I have used these little spring clamps for several decades. I always have some of them handy - a model train, a kitchen, an office, a garage, a tool box, even in my car. Can be used as clips in numerous model railways. The best zip ties for sealing groceries bags - french fries, frozen vegetables, etc. - are far better than the flimsy plastic zip ties sold for this purpose. So far I've bought them from a big hardware store, but this deal was too good to pass up. There can never be too many of these.
