Tritium Vial Huge 5.5 Green Self-Luminous, Very Bright

Huge 5.5 Green Tritium Vial, Self-Luminous, Very Bright. I made a Transparent Acrylic Cylinder packaging for the tritium vial, the end caps are not glued only pushed on and taped with clear tape so they don't open by accident. This is a continuous non-electrical source of illumination glows continuously for 10+ years. All the vials i sell are manufactured in 2022 so they have a lot of life left and are as bright as they come. In total darkness it is very bright! Even with the door open in the other pictures you can still see the green glow and of course in regular light you wont see anything. Please check out my other listings for more sizes. This listing is for one 5.5 inch vial, 4.98mm wide. Please feel free to ask questions! I don't want to disappoint anyone. Thanks for looking!
