Maratac Tritium Ember Glow Fob With Glass Breaker MAR-180

The Tritium Ember Glow Fob from Maratac is a great piece of kit that uses self-powered tritium, a rare element that produces its own light. It's perfect for telling keys apart, and its glow will help you if you lose your whole keyring in the dark. The injection-molded polycarbonate casing also houses a glass breaker for all your glass-breaking needs.
