So this is the official release announcement of the TEC-T3-6X Isotope Triode Fob, currently available on our website at http://www.tecaccessories.com/TEC-T3-6X Let's start with the pics! DESCRIPTION: The TEC-T3-6X Isotope Triode Fob is a keychain fob specifically designed to hold multiple self-luminous tritium vials. Tritium vials come in a variety of standard sizes and colors, and will glow for many years without requiring any type of "charging" from sunlight. This version of Isotope fob has 3 primary bores to house the tritium, hence the nickname "Triode". The Triode can hold several combinations of tritium vials, as each bore can hold either one 3mm x 23mm vial OR two 3mm x 11mm vials. Think of the color combinations! NOTE: THIS PRODUCT DOES NOT INCLUDE COLORED TRITIUM VIALS. YOU MUST PURCHASE THE VIALS SEPARATELY FROM A SOURCE OUTSIDE THE UNITED STATES. Unlike our conventional line of glow fobs, the Isotope was designed around the use of a glass tritium vial. This makes it different from our standard glow fobs as it will glow continuously without any type of charging cycle. The Isotope Triode is a titanium housing, bead blasted to a uniform matte finish. There are three primary bores to hold the tritium, and six grooves on the side of the housing to provide maximum tritium visibility, yet offers superior protection of the glass vials. Once the tritium is installed, you simply insert the included rubber plug (spares included), install the o-ring over the post, and attach the split ring. This prevents the tritium vials from sliding out, yet provides an easy way to remove the vials if you want to change the colors. Attach the Triode to your car keys or even a flashlight, so you can always find them when the lights go out. Attach it to your jacket as a zipper pull so your friends can locate you inside a movie theater or outside at night! You can clip it to a backpack, camping gear, or even to the pull chain on a ceiling fan...the uses are endless!
