I am selling a large tritium vial that measures 5mm x over 6" long. I like it I just want to direct the funds to another project. Asking what I paid $50 + shipping.
I guess I can not say for sure if it is or not. I can only say what I was told when I bought it. I was told it was new roughly 6 months ago when I bought it. One thing for sure is that the large vials like this are hard to find.
It's not extremely bright, but in the middle of the night it is quite bright. I've got one in my room on a shelf and I have to position it so I can't see it directly because it is distracts my sleeping.
