Where did you pick it up. There was a guy here a year + back that made custom mods. I have a couple. One a squonk and one a single 18650. Also had one that was a dyed wood. His name was Sonar 505. He's no longer here but I still regard his mods to be a higher quality. At least the 3 I've come in contact with were. I think
@JuicyLucy has a few of his mods still also. Maybe she can confirm is she's seen this one. That's all I've got though as far as help.
