I guess I might try some of the "
vape accessory" sites there are several ECF vendors and also perhaps sites like ebay or amazon. If you find no joy, maybe etsy, if you find a leatherworker you like the looks of, you could perhaps get something custom designed.
Best of luck, I have a few leather pouches and holsters for my
mods, but they were all made and designed by the husband. He's good with leather and wood. Woods, I guess I will say, to make that sentence less, well, there are lots of places to look, if you see what I'm saying.
Best of luck,
Anna
