Treknor Keeper Aluminum Waterproof Match Compass

I need something I can clip on my swimsuit during my vacation. I take a lot of prescription meds and want to be able to take a days pills with me. I hoped this would do the trick. I placed an ibuprofen tablet in the case and tightened as tight as I could. I dropped it in a glass of water. An hour later and the pill was dissolving in moisture. I can't imagine that this would keep matches dry. The o ring is extremely thin. I may keep it to carry things in a dry bag, but it is not waterproof.

very good item for those who do a bit of adventuring. keeps you matches dry but also is solidly built to keep them in one piece as well. good price point and very well made.
