Most food storage canisters are "Airtight"? which means they lock air in with the contents. This Kitchen Canister forces the freshness-destroying air out of the canister, extending the life of your coffee, tea, flour, sugar, cereal, seeds, herbs, nuts, pet food, or any perishable goods, to keep what's good today, good tomorrow too.
