This is a necklace for a total of three green 2mm x 12mm tritium vials.

The vials themselves are glued in with clear epoxy.

For prototyping I printed it with PLA and then had it printed for me in polished nickel steel.

To be transparent, I was inspired by this webshop: http://www.byinnovodesign.com/product-page/titanium-tritium-delta-pendant
