Tritium Keychain Flashlight

This is a tritium vial holder to be used as a key chain or pendant.

The holder is sized for a single 22,5mm x 3mm tritium vial.
To fix the vial in place push a 1mm x 2mm o-ring into the vial channel after the vial, a small groove will hold onto the o-ring and the o-ring will keep the vial in place. no glue needed.

This includes only the holder and nothing else, so you have to get the vial and an o-ring separately.
