The 5LB Coffee Reserve is your go-to bundle for buying in bulk without sacrificing freshness. It includes two Airscape® Kilo Coffee Canisters—each with a 2.5 lb capacity—so you can split your 5 lb coffee haul with purpose and precision. Use one Kilo canister right away with the original Airscape® plunger lid, designed to push out excess oxygen and lock in flavor. The second Kilo canister is upgraded with our Fresh-Port® Inner Lid and Airgone® Argon Gas, creating a sealed, oxygen-free environment that keeps your reserve beans fresh until you're ready to brew. Buying in Bulk just got THAT much easier Bundle includes: 2 × Airscape® Kilo Coffee Canisters (2.5 lbs each) 1 × Fresh-Port® Inner Lid – Kilo size 1 × Airgone® Argon Gas Can (good for up to 150 two-second flushes)    For optimal results when using Airgone®, keep the red straw detached from the Airgone® can when inserting it into the Fresh-Port® valve. Hold the red straw close to the end being inserted and apply gentle pressure until the straw can stand alone. Then, attach the Airgone® can to the opposite end and administer a 2-second flush to displace oxygen. Once worn in, customers should have no trouble using Airgone® to keep their products fresh.If you would like to speed up the wear-in process, take a paperclip and poke the blunt end through the Fresh-Port® valve. This should help widen the valve slightly while maintaining the silicone seal, preventing oxygen exchange!We cannot ship AIRGONE® to PO Box addresses, Alaska, Hawaii, or internationally (excluding most Canadian provinces). All AIRGONE® products will be shipped via UPS. Airgone Safety Sheet
