TYD DNA-MBK-GBY Tritium marker jewelry glow in dark pendant fob necklace:
$200.00

I WILL BE ON VACATION FROM NOVEMBER 30 THROUGH DECEMBER 5TH.

ALL PURCHASES DURING THIS TIME WILL OCCUR ON DECEMBER 6TH.

This the very first of its kind and I have not decided to make any more yet.

This will ship via EMS airmail with a tracking number.

Unlike every other tritium marker, this one is extremelycomplex to design and impossible to machine.

This design uses 6 small (1.5x6mm) tritium vials that are twistedin a DNA style helix.

The vial colors are alternating green, blue, and yellow.

Impossible to machine by CNC; it had to be 3D printed in matteblack steel.

After printing, I had to drill out all the holes to allowfor heat expansion/freezing and glue in the vials with UV activated glue.

THIS IS NOT A KEYCHAIN or KEYFOB!

Why? The vials are made of glass and having keys bump intothe vials might lead to broken vials.

You get the exact pendant with lanyard as in these photos.

Tritium self-glows a long time; it requires no charging.

In ~12.5 years it will still be half as bright as today.

It would make a very unique gift that lasts for decades.
