## Customer Reviews

### ⭐⭐⭐⭐⭐ Would buy again
*by A***. on 25 December 2025*

Great addition to any gear.

### ⭐⭐⭐⭐⭐ Tiny, Precise & Very Useful
*by M***. on 5 September 2024*

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.

### ⭐⭐⭐⭐⭐ Precious little EDC’s...
*by A***Y on 4 March 2021*

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...
