TEC-S311T Isotope Tandem Fob

Tandem Fob fits 3mm x 11mm Vial Perfectly

I first wrote a review detailing how the Vial kept falling out. This was due to the Vial Seller (Tritium Workshop) sending my the wrong Vials (not the Tandem Fob). I emailed them, they gave me a hasty response (considering timezones), and made things right by sending me the actual Vials I had ordered (3mm x 11mm). Tritium Workshop had great customer service along with TEC Accessories even though TEC Accessories was never in the wrong. If it doesn't fit, check the Vials. Great product!

Awesome

After getting a tritium vial, it's the perfect fob to attach between a pocket flashlight and pocket clip. With the vial, can find the flashlight in the dark when most needed. Thank you

Great keychain fob

Bought a few of these keychain fobs. Came nicely packaged and arrived super fast. Ordered my tritium separately from one of your recommended suppliers and they fit perfectly.
