Product Details

The versatile TEC-S311M Isotope Mini Fob is designed around the use of a glass tritium vial (not included), which will glow continuously for many years without need to charge it from sunlight or UV light. Three slots on each side of the housing allow for maximum tritium visibility, while still offering superior protection for the glass vial. Very similar to the TEC-S323 and TEC-S360 fobs, the shorter profile of the Mini Fob adds a subtle touch of luminous style to your keychain.

The Isotope Mini Fob is an economical way to add a functional glow to anything you attach it to. You can also change out the vial anytime you like for different glow colors. Use different colors to identify different sets of keys! 

Complete your EDC collection with the small, functional and stylish TEC-S311M Isotope Mini Fob, which provides just the right amount of light for locating items in the dark. Perfect for attaching it to your keychain, camping gear, zipper pulls on gear bags or jackets, or try it on the pull chain on your ceiling fan. Where will you clip yours?
