If you enjoy cooking or snacking trying to keep food fresh by clipping bags closed is a pain and usually not very effective. I prefer to use rubber bands to keep my bags closed for freshness so I keep an assortment on hand in my kitchen drawer. As a magician I use rubber bands for a variety of tricks that I perform so I like to keep a stock of various sizes on hand in my bag of tricks. These do the job nicely. About ten years ago my aging wisdom concluded that the world is actually held together by tape rubber bands and glue. "GOT RUBBER BANDS?"
I used them to hold Brio train tracks together for transport to grandkids. They were perfect! Just enough stretch to hold 6 track pieces together. No breakage so I suffered no sting :).
