Review : Olight S-mini Ti

That’s a tritium fob, this one is a Blackwater Kr36, identical to mecarmy ones…
It will glow for about 15years without any form of charging. Basically a radioactive (weak) element that glows…
If you want one similar for a good price, you could sign up for the Vollsion group buy that freeme is organising
I paid 33$ for mine, so this is a good price.
