Review on ☕ Airscape Ceramic Coffee and Food Storage Canister - Airtight Inner Lid with Two Way Valve for Enhanced Food Freshness - Glazed Ceramic with Bamboo Top, Medium 7-Inch, Obsidian Black by Mary Hovatter

Great idea but lacks the practicality. Let's say a company believes ground coffee stays fresher in an airtight container than it does in regular 12-ounce coffee bags. , then why doesn't it fit in the whole bag? The canister should be about 1/2 inch taller to accommodate the inner lid when pouring the entire 12-ounce bag. Then if you want the outer cap to fit as well, add another inch. So 1-1/2 inches higher would make it workable for a typical bag of ground coffee. Now for the outer shell. It seals so well it won't stay down. When you squeeze it, it rises again due to the air pressure inside. The design requires a method to allow air to escape (as in the case of the inner lid). Or they have to remove the gasket from the outer lid (it's supposed to protect the inner lid from dust etc. but doesn't affect the freshness of the coffee. I'd give that up and find a solution that's designed for the entire bag of ground coffee.
