Want a small waterproof firekit container

My firekit is basic and it's all I want to carry. I kept it in a metal Altoids tin until I upgraded to a longer ferro rod. The ferro rod won't fit inside, and I'd rather have a watertight solution anyway. Any suggestions for a small, lightweight firekit container? This will go in my backpacking pack so I want something more substantial than a ziplock freezer bag, but don't want the excess weight of a small molle pouch unless there was one with a watertight zipper.

Suggestions?
