So I pulled the trigger on one of these as I was placing an order with MM anyways. Basically a custom-printed ball jar lid with a plastic/nylon base. Solidly built, inexpensive, and available in your choice of several colors. I think it will be useful albeit it will only hold 2 or 3 smokes. Still a fun way to both carry tobacco and rep MM.
