The TEC Accessories Chain Reaction Isotope Fob is a combination of the popular Embrite Glow Fob and Isotope Tandem Fob, creating a tiny source of light with twice the glow! 

The Chain Reaction fob is designed around two light sources; the Embrite glow pellet (included) and a 3mm x 11mm tritium vial (not included). The Embrite pellet works by taking its 'charge' from sun or UV light, providing a bright glow once darkness comes. However, as the pellet requires a light source to recharge, this is where the tritium vial comes in as it can glow for years without needing to be recharged.

PLEASE NOTE: THIS PRODUCT DOES NOT INCLUDE THE COLOURED TRITIUM VIAL.
