This is cigarette box for 7 cigs, styled as a 6-shooter revolver drum. It kills, right? One cigarette per day - that's for a week! :) The cap is fixed on body with a thread, so no accidental opening in the pocket. Can be printed completely watertight (although, it might be tricky, and definitely will require a sealing rubber ring around thread neck). This one is for 8x84mm cigarettes. Theoretically, it can be scaled in slicer for other cig sizes.
