TEC Accessories Inc TEC-T323-2X Isotope PRE (Picatinny Rail Edition)

For the ultimate in one-of-a-kind tritium glow fobs, look no further than the TEC Isotope Reactor. The Reactor Fob is designed to hold three glass tritium vials (not included) which will glow continuously for many years without the need to charge them from sunlight or UV light. The virtually unobstructed view of three 3mm x 23mm tritium vials in different colors gives off an amazing glow, and the vials are well protected by the Ti-6Al-4V titanium construction and durable borosilicate glass window.
