MiiR Coffee Canister - fresh coffee every day MiiR Coffee Canister keeps your coffee fresh in the perfect environment. MiiR has been in the caffeine game long enough to know a thing or two about coffee. An interior accordion-style seal compresses to kick out oxygen and lock in flavour, and an easy-grip, simple twist bezel lid completes the closure. Fit to hold a bag of beans (whole or ground) that is under 340 grams. The Coffee Canister’s sleek silhouette can outfit any kitchen counter and travel near or far.
