I got the Brass Compass Capsule thinking it was going to be smaller than it was. I carried it around for two weeks and decided it was just to big for the key chain and would have to find another use for this quality piece. In case others might be interested here is a little bit about it. On the back side it has a very accurate compass. It will hold 7 large vitamin pills and sealed it is completely water proof. I do wish they would have made the compass part flat, it sits at a angle when you try and sit it straight up. So then I ordered the brass Pico Pull which was the perfect size for me. It will hold two regular sized Tylenol pills or for what I need migraine pills when I get one a couple times a year at unexpected times. It is also completely water proof. Hope this little review might be helpful for some that might be looking for something like these handy little containers?
