I have 3 zippered carrying cases, 7, 5 and 2 pipe capacity. I put a Bic and cheap tool in each. I have a rectangular plastic tub that's around 6" x 10" x 18" I carry tobacco in when driving on a trip. I don't like to have to think much about what I'm taking, I just throw a bunch of things in and latch the top. When flying, I generally just load one of my backpack pockets with tins.
