## Overview

The Tec Accessories Isotope Mini Fob S311M is a compact and stylish accessory made from durable stainless steel, featuring a bead blasted finish for enhanced grip.

## Description

The TEC-S311M 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 simply shorter in length. This allows you to attach the Isotope to smaller objects such as a keychain flashlight without interfering with its use. Since the vials are short, you get the added benefit of a lower cost compared to our full-length Isotope models. It's the perfect way to color-coordinate your items in a cost-effective manner. ** Please note this product does not come with a Tritium Vial**

- Material: Stainless Steel
- Overall Length: 20.5 mm [0.81"]

    No Tritium Vial included!

I am very disappointed, all of the images in the description show this glowing but without the vial of Tritium it's just a small metal tube! Utter rubbish!
