There's no worse feeling than dropping something in the dark, only to fumble around fruitlessly trying to find it. We've all been there — that's why Glow Rhino applied military-proven tech to solve just such a problem with its Tritium Glow Fob. The fob features a self-powered tritium lamp encased in a polycarbonate and CNC-machined, black nitride-coated stainless steel shell. The tritium lamp has a half-life of over 12 years, so you can buy the Glow Fob knowing it's built to last. If that's not enough to convince you, it also comes kitted with a glass-breaker tip for use in emergency situations.
