We love the look of old fashioned canning jars for storing rice, beans, oatmeal, or tea bags. You can find them a lot of places—flea markets, garage sales, and The Container Store—but vintage ones aren't often airtight, and new ones can be pricey. These are made from Italian glass, look weighty, and don't cost a fortune.
Faith has already mentioned how helpful it can be to save empty jars and reuse them, and that's a great option. We certainly don't want you to add more clutter to your kitchen by buying new jars if you have some you can use.
However, if you are in the market for uniform, airtight storage canisters and want something glass rather than plastic, these from Sur La Table look beautiful. We haven't held them in person, so we're not sure how they'd compare to similar versions at The Container Store (which sells French jars and generic, non-fancy-European ones, all for around the same price as these). But the largest size, which is tall and holds 2 liters, is $6. Smaller sizes start at only $3. Many plastic storage containers we've seen are much more expensive, and these are prettier.
