I recently bought a 1lbs box of the Bold KY Flake. It already has a few years on it. The seller stored it in a Mylar bag but removed it before shipping so that it would fit in a flat rate box. My question is how to store it. Should I divide it up in 1-2 oz packeages and only open what I want? Or store it bulk and open it in order to pull 1-2 oz out at a time? The second question is rather I should use ball jars, vacumesealed bag (I have the machine), or ziplock bag?
