I also like jars that are clear enough to let me see the contents easily. If I plan to use them for food storage, I want glass that is food-safe and built to handle regular washing without clouding or cracking.
Why the Lid Matters to Me
I never ignore the lid because it makes a big difference in how useful the jar is. I usually look for lids that seal tightly so my food stays fresh longer.
