The Timemore Glass Canister 2.0 (800ml) is a precision vacuum-sealed storage container engineered to preserve the freshness of coffee beans, tea leaves, and dry goods. Constructed from durable, lead-free borosilicate glass, it utilizes an intuitive dual-button lid mechanism. The primary button manually extracts ambient air and CO2 to establish an airtight vacuum, while the secondary button instantly normalizes pressure for easy opening. This system actively prevents oxidation, moisture ingress, and flavor degradation.
