The stainless steel canisters (1 qt, 2 qt, and 3 qt set) from FOXRUN are stylish and practical with a unique and functional easy view plastic window that allows to track supply levels and content without labeling. While the 1 qt canister (home-made cookies were still moist at day 5) and the 2 qt canister (coffee beans were still shiny/fresh and the aroma was strong at day 7) had a secure airtight seal, 3 qt canisters' seal was unfortunately neither secure or airtight (might be a defective sample) allowing the flour to absorb moisture at the end of a week.
