Don't buy those crappy plastic bag-clips to hold chip bags, flour bags, etc closed. They're unsatisfying, they wear out and bend, and they just add more plastic pollution to the world.
Instead buy more binder clips. They're made from spring steel, they're strong as hell, they almost never wear out, they can be used to close bags, as small clamps, as hangers for almost anything in a pinch, and they're amazing for building pillow / blanket forts.
I have some from my grandma that she bought 30 years ago and they work just as well as the ones I bought a year ago. The only risk with them ever is rust, and you can just scrub that off with vinegar, add a brush of paint and it's fixed.
Truly some of my favourite robust little items.
