As stated in Flavours Magazine.....

Sometimes there are products that are all the sizzle, but no substance. In this case, you don't have to worry. The shiny (and almost lickable) vibrant red or blue coffee canister will add punch to your kitchen decor as well as protecting your coffee beans (or tea). Its unique design goes beyond mere aesthetics as this canister actually presses out air to vacuum seal the contents when the lid is put on. Too Cool!!!
