I'm always just throwing mine in my purse or my pocket (which is uncomfortable). I have a PCC but that doesn't provide easy access.
No seriously, it is always in my hand. If I am not holding it I have a little purse like pouch I bought that I wear that I can put it in if I am out and about. It's about 8 inches by 5 inches and has a strap like a purse but I love that it has zippered compartments that make it perfect for batteries atties, or bottles of juice in addition to 2 larger zippered pockets for the mod or mods. I love it and only paid $3.
(JK lol ... No way I would ever wear either. Guys, you need to know how bad these lanyards look lool.) Ecigs are strange anyways .. Only here do people turn it into a hobby.
