I love glass food storage containers since they can go from the freezer to the fridge to the microwave all without any issues. Plus they're sturdy! I usually purchase the GlassLock brand but I wanted to try Martha's brand because of the flexible lids. I loved the variety of sizes in this collection. The smaller ones are great for small bits of leftovers like applesauce or that last bit of mashed potatoes. The medium ones are great for leftover pieces of roast. I really like the one that is shaped almost like a loaf pan. For some reason that is the one that I grab most whenever I have to put something in the fridge. It just is such a great shape and I prefer it over the round ones. I also love to give these to family members when I'm bring them a meal as they seal super tight and I don't have to worry about them leaking in my cooler on the ride over. I hand wash mine so I can't say how the lids would hold up in the dishwasher, but I've had absolutely no issues with mine warping or not fitting well.
