TEC Accessories - ISOTOPE S323 - Glow in the Dark Stainless Steel Housing for 3mm x 23mm Tritium Vial (Not Included) - Keychain Fob - Camping Accessories - Glow Sticks - Gifts for Men

NOTE: THIS PRODUCT DOES NOT INCLUDE A TRITIUM VIAL. The TEC-S323 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. 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. 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.
