A glow tube, a metal shell, and a keyring loop. That is the formula most brands follow, and it has not changed much in years. Xedge took a different approach with NoxTi, a Kickstarter project that fits a tritium vial, a glass breaker tip, and Gr5 titanium into something that weighs 10.7 grams and measures 45 millimeters end to end. The campaign has already blown past its funding goal by more than 12,000 percent according to Kicktraq tracking data, with nearly three weeks still on the clock.

That 45-millimeter body is smaller than most car key fobs. It weighs less than two quarters stacked together. The shell is cut from Gr5 titanium, the same tough alloy used in jet engines, high-end watches, and medical implants. It fights off rust, resists scratches, and barely adds weight to a keychain that already has plenty. Inside, a sealed tritium vial sits behind a quartz window, glowing nonstop for a rated 25 years with no batteries, no charging, and no outside light needed.
The science behind that glow is simple. Tritium is a form of hydrogen that gives off weak radiation as it breaks down. When that radiation hits the coating inside a sealed glass tube, the tube lights up. The radiation is too weak to pass through skin or glass, which is why tritium has been used safely in watch dials and emergency exit signs for decades. NoxTi puts that same science on your keyring, giving off steady visible light in total darkness without you doing a thing.
What Gr5 titanium brings to a 25-year glow
The material tells you a lot about what Xedge was going for. Gr5 titanium, also known as Ti-6Al-4V, is stronger than stainless steel for its weight. Xedge used it to build a shell that protects the tritium vial without adding bulk. The quartz window over the vial is a step up from the acrylic or resin covers found on many tritium products. It handles impacts better than regular glass and resists scratches more easily, which matters when the keychain is bouncing around with keys, pocket knives, and whatever else you carry every day.
At 10.7 grams, NoxTi weighs slightly more than a typical house key. That is on purpose. Xedge kept the part count low and the shape tight, so the result sits on your keychain without tipping the balance or creating a lump in your pocket.
The glass breaker built into the opposite end turns NoxTi from a glow fob into an emergency tool. Xedge lists it as a glass breaker but has not shared breakage test results or details about the tip design. Most dedicated car escape tools use tungsten carbide tips because carbide is much harder than glass. Gr5 titanium is only about as hard as tempered glass, so whether the tip performs as well as a carbide breaker in a real emergency is an open question. As a backup feature on a 10.7-gram keychain, though, the intent is clear.
Swappable vials add a layer most competitors skip
NoxTi handles its tritium vial differently from most products in this space. Instead of sealing the tube inside the titanium body for good, Xedge built a swap system that lets owners change colors. Kickstarter lists six color options: orange, ice blue, purple, green, yellow, and red, chosen after the campaign ends. Different coatings inside the vial create different colors, and the ability to rotate through them adds a level of customization most tritium keychains skip entirely.
That swap feature also solves a lifespan problem. If a vial gets dim or cracks over 25 years, you replace the vial instead of throwing away the whole keychain. The titanium body keeps working, which is a big step away from the sealed, single-use design most competitors use.
Over 2,200 backers in under two weeks
Xedge launched NoxTi on Kickstarter on March 19, 2026, with an HK$10,000 funding target, roughly US$1,280. According to tracking data from late March, the campaign appears to have crossed HK$1.25 million (about US$161,000) from what the tracker lists as over 2,200 backers. If those numbers hold, that would put the project past 12,500 percent of its original goal with roughly 19 days still remaining.
The campaign page lists both luminous glow-in-the-dark vials and true tritium vials across different reward tiers, with tritium options appearing to be priced higher. Based on the available tracking data, the average pledge comes out to around US$72, a figure that likely reflects a mix of entry-level luminous tiers and higher-priced tritium bundles.
That kind of early traction is unusual for a category this niche. Tritium gear has a dedicated following that tends to treat glow products the way watch collectors treat lume, and NoxTi seems to have hit a gap between inexpensive tritium fobs and pricier custom titanium pieces. Whether the momentum holds through the rest of the campaign remains to be seen.
