The list author says: "I have spent some time looking for glass food storage containers that would be useful for food storage at home and to send in my toddler's lunches. Here are the ones I've tried, and what I think of them."
"Have had these the longest (5 years). The smallest round containers are good for my lunches, but are a little too big for my toddlers. The seals on the lids hold up well. I don't use the square containers much."
"I have had these for about 2 years. I used them at first for baby food "pods" that I had frozen and now they are great for my son's lunches. They are the perfect size, but unfortunately the lids do leak a little."
"These are great for home, but the smallest container is too big to send for lunch. They seem to seal and wash well. The lids are a little bit of a pain because you have to take the seal out to put it in the dishwasher, but it probably keeps them cleaner. I haven't had these too long, so we'll see how they hold up. It's nice that they stack well."
