I forgot to mention, for those big items and larger quantities, Mylar bags up to 5 gallons in capacity are available.In some cases, I'll have no other choice! The Kendal Plug and the Wessex Curly Block are too big to put in a jar unless I cut them down, which isn't something I want to do ahead of time.
But any tobacco quantity short of a leaking 14 oz tub should fit in a one gallon bag.
