These are incredibly handy - and you can get like 6 for a dollar.
I keep a bunch of them around the kitchen, and a few in other rooms around the house.
I use them for sealing food bags all the time, but also added protection when transporting things in my bag that could spill or leak.

I have so many of these clips in my utensil drawer in my kitchen. They come in so handy for various things. I even use them to hold the page down on my cookbooks, when I am trying a recipe. That way, if the book gets knocked over, my page will be marked with the clip.

Oh these are fantastic! Great price and so useful. Different sizes come handy.

These Dollar Store bag clips are so handy. I use them on all sorts of food bags to keep the content freshly sealed. They come in a variety of sizes that make it very convenient to use. I keep them in my drawer and pull them out when needed. Easy to use and store. They work really well and are so inexpensive.
