Isotope S360 - Stainless Steel, Tritium Vial Housing (3 mm x 23 mm) - Housing for EDC Vial Tritium Keychain - Cool Keychains Accessory for Camping and Survival Gear

I’ve kept this on my keychain for a while now and it still looks perfect! Even after some abuse, the glass has not broken. There’s no risk of the tube falling out like others i have tried. It might be a bit pricy but it fits perfectly and looks great. Overall i am happy with it

Beautiful design, high-quality machining and construction, and easily the smallest tritium keychain holder on the market!I haven't had it for long, but it's been thrown around for the past week or so, while attached to my Airpods case, and has had no issues with durability/protection for the trit vial, so far! The design is nice - it basically allows the most light through possible, while still protecting the vial very effectively - and looking cool & stylish to boot. It came well packaged, in a little plastic vial (which I re-used to store my extra trit vials!), and with an even smaller plastic case containing several extra rubber plugs for the end, in case you lose any.I have another keychain tritium light that I bought from Ant Designs (which is also where I purchased my vials from - very reasonable pricing, and surprisingly quick shipping!) - it's equally well built, a bit more protective (it has an inner clear plastic shell, and spring-loaded shock absorbers on either end) - and the design possibly allows a little extra light through, as the windows are bigger - but it's also significantly larger overall, more expensive, and due to the design of the windows (long vertical openings, alternating with long vertical bars), the light can also be fully obscured, from some angles. This one on the other hand allows a little less light through, and is likely less protective - but the design of the windows allows light through regardless of what angle you're looking at it from, and it is easily the smallest a keychain light (for a 3mm x 23mm tritium vial) could be, while still being functional!IMPORTANT: this does NOT come with the actual tritium vial included! As long as you know that going in, I think you'll be fairly happy with this product! (Sellers can't sell tritium vials on Amazon, as it's a radioactive substance, so you have to order it from other sources - see my above comment for one option). Is it a bit expensive, considering that it doesn't even include the vial? IMO, yes, and no. It's absolutely worth it to me, for the quality of the machining, and the elegant design aesthetic - however I do think that the companies that sell these are also marking them up slightly, due to the cache associated with having a "radioactive lantern" - even though they don't include the tritium vial itself 🤷🏻‍♀️. Still, since that seems to be the all-around going price for these products at the moment, and as the design and build-quality is very good, I don't feel too bad paying that amount, for this product, and would absolutely recommend it to anyone who asked!

It is well made and a great idea but I purchased 3 Tritium sticks and they don’t glow for nothing you can’t buy the real good tritium in the united state you would have to buy from a foreign country that sells high quality tritium and it is very expensive

Very slim and easy to see the tritium tube. I like it a lot.

I put a blue tritium vial in this in 2016, and have had it in my pocket with my keys ever since. It is very good looking and strong. No complaints at all. If I wanted another tritium vial I would definitely buy one of these for it.

This USB a very cool looking piece that is well manufactured. The craftsmanship is such a tiny piece is superb... why only two stars you ask? This is just flexible enough to bend where your $25 vial inside will explode in your pocket. I purchased 3 of these and 3 vials. 2 of them cracked in a week. I use the third one hanging from the ceiling fan chain in the bedroom. Too fragile for EDC keychain.

The fob is very well made. It fits the tritium vial exactly. I searched on Amazon and found the vials. The kit comes with a little container holding the plugs and the split rings The actual fob has been machined very well. You couldn't ask for a better manufacturing job. But a single tritium vial does not give off much light. I was hoping to use the light to find a keyhole in the dark. It won't work for that because it is too dim. But it will work very well to find something in the dark. I may attach it to my keys or to a flashlight. I took off one star because I was hoping for a brighter fob. But it is still pretty cool and it will be useful.

A solid product for holding a tritium vial. Has safely contained my vial on my key-chain for a few weeks now, and is quite sturdy. It comes with extra rubber gaskets and ring as well. I recommend using two gaskets, as the standard sized vial will be a little loose with only 1 gasket.
