NOTE: THIS PRODUCT DOES NOT INCLUDE A TRITIUM VIAL. 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!

  • Stainless Steel Construction: Made from custom-machined stainless steel, this fob securely holds a single tritium tube (not included), making it a durable and compact addition to your gear.
  • No More Lost Items: The stainless steel feature of this tritium housing ensures you’ll never lose your gear in the dark. Perfect for easily finding keys, camping equipment, or essentials during power outages.
  • Designed for Tritium Vials: Specifically built to house a 3mm x 11mm tritium vial, this tritium light housing is ideal for those who want reliable, keychain accessory. Note: Does not include the tritium vial.
  • Stylish & Practical: With horizontal slots to enhance the visibility of the tritium vial, this tritium glow fob housing adds a sleek and functional touch to your everyday carry gear.
  • Multi-Purpose Use: Whether for keychains, zipper pulls, or emergency gear, the Isotope Tandem is a stylish and practical addition to any survival kit, backpack, or everyday carry setup.
  • Two Attachment Holes: The dual split ring holes allow the Tandem to be inserted between items such as your keychain and your key. This allows you to add multiple Tandems to your keychain and color code your items with various tritium vial colors.
