IMPORTANT NOTE: This product DOES NOT include tritium vials. Click this website to purchase them. https://tritiumkeychains.com/product/3mm-x-11mm-tritium-vials-9-colors-available/ The TEC Isotope Atom is a coin style titanium fob designed to hold numerous glass tritium vials (not included), which will glow continuously for many years without the need to charge it from sunlight or UV light. This version of our Isotope Fobs has 6 individual bores to retain the tritium vials, which are visible from both sides of the housing. This offers maximum visibility of the tritium glow regardless of which side is facing up. The Atom can hold several combinations of tritium vial colors, allowing you to be as creative as you like with color and placement of the vials. It will accept up to six 3mm x 11mm vials, and they are extremely easy to change out so you can add more vials or switch up your color design. Once you install the tritium vials into the bores, the outer groove of the disc accepts an o-ring which holds the vials in place. If you ever want to change or add tritium vials, simply remove the o-ring from the groove, make your desired changes, then insert the o-ring back into the groove. It's that simple. Locate your bags in that pitch-black hotel room, find your keys in the dark, or simply have the most unique glowing necklace charm. Whether you use the Isotope Atom as a functional zipper pull or to simply identify your gear, there are a multitude of uses that will look absolutely amazing.
