These canisters are heavy-duty plastic and look very durable. You have to consider the space the lid takes in the canister because it limits how much the canister can actually hold. I tried storing fresh ground coffee beans in it but I think I filled it too full because it wouldn't hold the vacuum. I stored cookies in the canisters and put them in the freezer. They are holding the vacuum perfectly.
