YETOOME Sealing Clips for Food and Snack Bag - 12pcs Plastic Bag Clips in 3 Sizes, 2.7/3.7/5.7inch

I actually use this to seal off large balloons so they can be deflated and reused and they work fantastically for that. I’ve only had one or two break in the few months that I’ve been using them for my application so I’m sure they’ll be perfectly adequate around the kitchen :).

CrapThey break super easy.
