After years of buying-using-tossing cheap plastic storage containers, I decided to upgrade to quality glass versions. I bought a couple of small bowl containers and liked them so much I went for this bigger set. OK for the freezer, oven, microwave, and dishwasher, made of nice heavy glass with a one-piece lid that fits tight but is easy to remove. And it looks beautiful in the refrigerator or on the dining table!As for size: the big bowl can hold an entire cut-up melon, the medium bowl holds a bag of baby carrots or a container of strawberries, and the smallest is good for prepped foods like diced onions, peppers, etc. I also use these to quickly microwave side dishes for dinner: they hold enough food for several people, look pretty to pass around the table, and store any leftovers as well. I prefer this one-piece rubber lid to the "snap-on" style or the ones with a separate gasket; it's easier to open (and for lazy kids to close), and it's still airtight.I've had other Anchor Hocking glassware in the past, and the quality has always been consistently good. Yes, it seems a little pricey, but over the long haul it's worth the investment in my experience. I've already started buying the other sizes and shapes to slowly replace all my old containers. Eventually my refrigerator, freezer, and pantry might all look as beautiful as the modern homes I see in films and in magazines!
