TEC Accessories Isotope S360 - Stainless Steel, Tritium Vial Housing (3 mm x 23 mm) - Housing for EDC Vial Tritium Keychain - Cool Keychains Accessory for Camping and Survival Gear;

NOTE: THIS PRODUCT DOES NOT INCLUDE A TRITIUM VIAL. YOU MUST PURCHASE THE VIAL SEPARATELY. The TEC-S360 Isotope Fob is a keychain fob specifically designed to hold a standard 3mm x 23mm self-luminous tritium vial. Tritium vials come in a variety of colors, and will glow for many years without requiring any type of "charging" from sunlight. This version of Isotope fob is very similar to our TEC-S323 fob, however the viewing slots have been modified. The alternating slots have been rotated 90 degrees to increase the view of the tritium vial throughout a 360 degree rotation around the housing. Hence the model number "360". It makes for a very stunning visual effect. 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 alternating slots on the 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. Once the tritium is installed, you simply insert the included rubber plug (spares included) and attach the split ring. This prevents the tritium vial from sliding out, yet provides an easy way to exchange vials if you want a different color. Attach the TEC-S360 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!
