Inspired by the Marvel Universe, part of "The Rings of the Gauntlet of Power" collection.
Made to fit one 2x12mm and two 2x6mm tritium vials.
Shapeways only produces the rings. you'll need to source the tritium. I've provided vial size info in the description of the rings. Please educate yourself on the potential health risks of tritium and the import restrictions for your respective country.
