OXO Good Grips containers

These are kind of expensive, but they have everything that I have ever wanted in a storage container, so I was excited when OXO introduced these:

First of all, they have square corners, which means no wasted space in your cabinets. And, they are stackable in various configurations, which means no wasted vertical space! They also create a suction seal when you close them, so things stay fresher longer, and no worries about bugs (for those of you in tropical climates).

The only drawbacks are that they are a little pricey, and they are not dishwasher safe. Still, if you can afford it I would recommend getting some skinny but deep ones for your staples (flour, sugar, coffee, etc.) so you can make the most of your cabinet space. You could get smaller ones for coffee and tea and stack them. I use a lot of dried ingredients that come in unwieldy plastic bags, and these would tidy up my cabinets in no time. Ooo, the possibilities!
