"Titaner" packaging with a "Lifesaver" for size perspective.
The Titaner bottle, a cheap aluminum "Nitro" pill bottle from Wal-Mart, and the Ti "bill holder" you see on the web.
These two Titanium pill/bill cases are a lot nicer then the ~$5 cheap import aluminum "nitro pill" cases you see everywhere. The Titaner is apparently designed to hold CR123A batteries but, its diameter is about the same as a nitro pill case. It is a little longer which is nice if you have some of those "horse" pills as part of your daily meds. I like the smaller diameter of the "bill case" but, it is a little tight for comfort for my larger pills. For aspirin, allergy tablets, and similar things it is a really nice size. Plus it makes a great way to carry some emergency money if you are out jogging or riding a bicycle.
Both of these appear to be super durable. While I haven't tested them for "yield strength" I'm sure I could drive my pickup over them in a parking lot without crushing them. They are not "too heavy" IMHO but, they are heavy enough to actually feel them in my pocket which is nice when I'm in a hurry to leave the house.
While I would have been happy with the "old" stainless steel nitro pill cases formerly available everywhere, it seems the really cheap "Chinese" imports have made them a thing of the past unless you are willing to spend ~$30 or so for one. At that pricepoint, I'll take Titanium. Both of these seem to made from the same material commonly found in pocket knife liners but, the bill case is a darker color then the Titaner battery container.
