# Glowing Titanium Keychains NoxTi Keychain Uses Tritium to Emit Continuous Light Without Batteries By Amy Duong | Published 2026-04-11 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/noxti References: [kickstarter](https://www.kickstarter.com/projects/459774293/noxti-a-titanium-glow-tube-light-for-everyday-carry?ref=a3av9g)  The NoxTi keychain presents a compact lighting object built around a tritium vial housed inside a [CNC-machined Grade 5 titanium body](https://www.trendhunter.com/trends/tiarc). Measuring 45mm in length and weighing approximately 10.7 grams, the cylindrical form encloses a quartz tube with high light transmission, allowing the internal glow to remain visible from multiple angles. The tritium element emits light continuously through radioactive decay interacting with a phosphor coating, requiring no charging, wiring, or external power source. The construction includes a modular internal system secured by silicone O-rings, allowing the vial to be removed and replaced after extended use. The titanium shell features cutouts that expose the floating core, alongside a [keyring attachment](https://www.trendhunter.com/trends/z3ro-mini-knife) and a [ceramic-tipped glass breaker](https://www.trendhunter.com/trends/timav-nextool) integrated into one end. It is available in multiple color variations and finishes.
