The large waterproof match case, much like the small one, keeps matches dry and unbroken. In this case, many, many matches. It has knurled caps which are perfect for striking your strike-anywhere matches upon. And... the waterproof match case is obviously... waterproof! It is sealed with rubber o-rings, and might I also add, is a mighty durable container machined from solid brass. This container can be carried in a pocket, glove box, or survival kit. A key ring style is also available, and can be clipped wherever it would be most handy.
