I use the smallest size otter box for my kit. An altoids tin just barely fits inside. I am currently trying to decide how much I like it. It holds a little more than an altoids tin, but is also slightly bulkier. It is completely waterproof though, so if that is a big issue you should definately check it out. Probably a bit large for denim jeans pocket, but easily fits in BDUs or a coat pocket, and has a nice lanyard attachment. I believe it also floats, but I haven't check that yet. They aren't any more expensive than buying a tobacco tin with the tobacco in it. I recommend checking it out, and seeing if it works for your particular preferences. It has alot going for it... I also have the larger version for a backpack kit.<br><br>Take care,<br><br>Greg
