The TEC-S311T Isotope Fob is a keychain fob specifically designed to hold a standard 3mm x 11mm 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 longer TEC-S323 and TEC-S360 fobs, however it is shorter in length and has split ring holes at each end. This allows you to attach the housing between two items, or in tandem, such as your key ring and keys.
You can then identify objects by color, such as your work keys and your house keys. And since the vials are short, the added length to your keychain items doesn't grow significantly and you also get the benefit of a lower price point. It's the perfect way to color-coordinate your items in a cost-effective manner.
NOTE: THIS PRODUCT DOES NOT INCLUDE A COLORED TRITIUM VIAL. YOU MUST PURCHASE THE VIAL SEPARATELY - AS YET WE DO NOT STOCK THIS SIZE SO WILL NEED TO BE PURCHASED ELSEWHERE.
