TEC-S311T Tandem Isotope Fob, a Stainless Steel housing with Black Diamond Carbon Coating for tritium vials - by TEC Accessories

Great addition to any gear.

This is a two-ended holder for a single, small tritium glow-stick. It is precisely machined, durable steel and useful for many applications. Item arrived promptly and was just as advertised.

This keychain has been great! It is nice and sturdy and the metal is nice in appearance and quality. Plus you can do lots of cool and different things with it. I have been using it on my key ring but, in the future, I may clip it to my pack. I would like to get more of them but, in general and especially with the tritium factored in, they are pricey. That IS part of what makes them precious, though...

I know it’s just a key chain but it’s pretty cool knowing I have a perpetual light that doesn’t need to be recharged. My only criticism for this particular keychain is that I wish they made a version that didn’t have the tandem key ring hole as I bought a few of these for Christmas gifts and think they are cooler as something for a key chain instead of a tandem item.
