After owning the Titanium model for several months. The best use I have been able to come up with is to store micro SD cards. Its seems to be what these were designed for since they fit perfectly.
I use my titanium to store my backup fire starting tinder. I did appreciate the internal O rings, but wanted visible ones, From my kit of O rings, the best fit (for outside) is shown in the pictures along with the finished result.
I have several capsules from CC spread between my house keys, go bag, and battery pouch. They're perfect for keeping a dose of ibuprofen handy without lugging a whole bottle. Nothing quite like having a headache or other pain come on and being able to shoo it away. But this one, the A/B, gives me that ability AND a way to bring a dose of allergy meds in the same container but separated. It does take up a good amount of size on my keyring, but I really don't notice it in my pocket. Gotta love that miracle metal vs. brass or steel!
