I have tried to follow this drop, but I have to admit that I just don't understand it. Do you have to buy vials (as an extra purchase) and then put them in, somehow? How long do the vials last? I'm just don't understanding it. Sorry.

brenda52411You buy the actual vials separately. I got mine from a site called mixglo, they have a lot of different sizes and colors. Tritium starts at full brightness and dims over a period of 25 years. (it has a half-life of 12.5 years). The vial simply slides in through the top of the cylinder and is held in by the key chain ring.
