Its corrosion-resistant, bead-blasted finish and multiple visibility slots maximize the vial’s continuous glow without charging, making it an indispensable, stylish, and durable everyday carry accessory for professionals who demand reliability and subtle sophistication in low-light conditions. ## Description NOTE: THIS PRODUCT DOES NOT INCLUDE A TRITIUM VIAL. The TEC-S323 Isotope Fob is a keychain fob specifically designed to hold a standard 3mm x 23mm self-luminous tritium vial. Tritium vials come in a variety of colors, and will glow for many years without requiring any type of "charging" from sunlight. Unlike our conventional line of glow fobs, the Isotope was designed around the use of a glass tritium vial. This makes it noticeably smaller than our standard glow fobs, and allows it to glow continuously without any type of charging cycle! The Isotope is a stainless steel housing, bead blasted to a uniform matte finish. There are 7 slots on each side of the housing as well as a hole in the bottom to provide maximum tritium visibility, yet offers superior protection of the glass vial. Once the tritium is installed, you simply insert the included rubber plug (spares included) and attach the split ring. This prevents the tritium vial from sliding out, yet provides an easy way to exchange vials if you want a different color. Review: This tiny little keyfob is well made and very durable. It does an excellent job protecting the vial held inside it. I'm pretty rough with my keys, tossing them on tables, dropping them, swinging them around in my hand--even though all that, this fob protects the vial inside just fine. And it looks nice to boot. This fob takes a 3mm x 22.5mm vial, and the fit is perfect. Note that the fob comes with two rubber pads plus a keyring. The two rubber pads do not mean you get one extra! Use both by placing one in the bottom of the fob before you insert your vial, then use either the vial itself or something like a coffee stirring rod to push the rubber piece down. Insert your fob, then squeeze in the second rubber pad and push it down. There will be enough clearance between the keyring hole and the top of the rubber pad for the keyring to go in on top of the pad, keeping everything in place unless you remove the keyring. If you need to remove anything, you'll need to remove the ring, then use a very fine tool to push up from the bottom on the bottom rubber pad. This will force all the bits up and out. 12/30/2015 Edit: 6 months and still good as new. Durable little thing. Review: Very solid little fob. Seems to be very well crafted. ## Features - Stainless Steel Construction: Made from corrosion-resistant stainless steel, this fob securely holds a single tritium tube (not included), making it a durable and compact addition to your gear. - No More Lost Items: This rugged tritium housing ensures you’ll never lose your gear in the dark.

Seems to be very well crafted. ### ⭐⭐⭐⭐⭐ Review *by J***S on 16 May 2016* Fit and finish are fantastic. Holds a 3x22.5mm vial perfectly. Mine also shipped with two rings and three small rubber plugs to ensure the vial does not float freely back and forth within the fob. I only needed to use one of the rubber plugs (and one ring, obviously), but I am a big fan of vendors who provide extra components. I have dropped my keys and the vial has been fine. I also don't see how the fob would flex very easily, but granted, it's not a solid cylinder wall due to the cutouts, so I suppose with force it would flex. I just don't subject my keys to that much abuse. ;) In general, I am extremely satisfied with every aspect of this product except its price. $19.99 seems to be the point beyond which this seems fairly pricey, especially when one considers you also need to drop $20 on a vial. Oh well, you can pay less for lesser quality. I decided not to cheap out. BTW, with regards to the vials, green is definitely the brightest, but don't believe claims of "daylight bright". Not given the size of the vial. I have purchased green vials from multiple sources and their brightness is all about the same, which is a pleasant glow in darker lighting conditions. ## Frequently Bought Together - TEC Accessories Isotope S323 - Stainless Steel Lantern Design Housing for 3 mm x 23 mm Glass Tritium Vial (Not Included) - Everyday Carry Tritium Keychain Accessory - Cool Keychains Accessories - sayram 2pcs Glass Luminous Tube, Rare Earth Luminous Stick, Glow Bar in The Dark Tril Vial Alternative, DIY for EDC Accessories Decoration - TEC Accessories 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 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/404972256-tec-accessories-isotope-s323-stainless-steel-lantern-design-housing-3](https://www.desertcart.vu/products/404972256-tec-accessories-isotope-s323-stainless-steel-lantern-design-housing-3) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
