We only use aircraft-grade titanium metal in our oil vials, because it won't be broken down by the oil you carry. PocketPro Titanium Oil Vials are perfect for carrying essential oils, religious oils, and more. You could even throw your favorite hot sauce in there if you need to. 

It comes with a metal clasp to attach to your key organizer, a fob, or a key ring.
