What do you mean by containers? I imagine almost all pipe pouches are soft for a reason. They are meant for a couple days worth of baccy and a pipe or two, and ease of transportation is key. Any type of hard container makes the transportation much more difficult. I have a cheap one that has a small pipe pouch that has a separate tobacco pouch with 2 snaps on it and snaps to the inside of the pouch. I guess you could make multiple tobacco pouches for it, and that would fill your need. I kind of like the look of these. I think he makes them with custom liners sometimes, too.

Sounds like a fun project, though. I think I remember seeing some of your work on the old site with the mason jar koozie. Those were pretty darn cool.
