Tritium-Vials

Shop tritium vials by size and color, in 1.5x6 mm, 2x6 mm, 2x12 mm, 3x11 mm and 3x22.5 mm. Green is the brightest color at every vial size. Every vial is a Swiss-made tritium vial, inspected on arrival, and glows for up to 25 years, with no charging or batteries needed. Fits our titanium keychains, fobs and tools, or buy the vial on its own.
