The Merkava Isotope Dual Tritium Fob is a keychain fob specifically designed to hold 2 standard 3mm x 11mm self-luminous tritium vials. Tritium vials come in a variety of colors, and will glow for many years without requiring any type of “charging” from sunlight or artificial light. Unlike our conventional line of glow fobs, the Isotope was designed around the use of a glass tritium vial. This makes it noticeably smaller than our standard glow fobs, and allows it to glow continuously without any type of charging cycle! The Isotope is a stainless steel housing, bead blasted to a uniform matte finish. There are 7 slots on each side of the housing as well as a hole in the bottom to provide maximum tritium visibility, yet offers superior protection of the glass vial. Attach the Merkava Isotope Fob to your house/car keys or use them as a necklace or earrings, 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 theatre 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!
