Three vials. Continuous illumination. No charging required.
Choose your three colours of tritium vials
The TEC Isotope Core is a titanium fob designed to hold three 3 mm × 23 mm self-luminous tritium vials. Based on the T9 Embrite™ Glow Fob, it replaces the glow core with a translucent resin insert that displays the vials through the housing.
Once installed, tritium vials glow continuously for many years without sunlight, UV light, batteries or charging.
Designed to showcase tritium
The precision-machined Grade 5 titanium housing has six viewing windows, alternating between slots and perforated patterns. Light from the three vials can be seen from multiple angles, creating a distinctive 360° effect.
Mix three vial colours or choose matching colours for a consistent glow. The resin insert holds the vials in place, and they can be removed and replaced if you want to change the look.
Made for everyday carry
Lightweight, strong and corrosion resistant, the Isotope Core can be attached to keys, a zipper, backpack or gear bag using the included split ring and snap clip.
No charging. No switches. Just continuous illumination.
