These canisters are made of a clear BPA-free acrylic. While light, they are very strong. And because of their tight hermetic seals, they're ideal for storing coffee, because the seals will keep the coffee beans from drying out. The clear acrylic makes it easy to see when your coffee is running out.
Their wide opening makes these ideal for your coffee, because you can easily put your hand through the top to scoop out a serving of coffee. Store the scoop in the canister with your coffee, so that it's easy to find.
These canisters have a 5" exterior diameter, so they will fit nicely on your backsplash. They come in three sizes: the 4.75" tall canister will hold a pound of coffee beans; the 8" tall canister will hold about 1.8 pounds, and the 9.25" tall canister will hold about 2.2 pounds of coffee beans.
If you ever wash them, they should be hand-washed, and not put in the dishwasher. Also, don't put them in the freezer, as you'll damage the seals.
