Hey guys I'm new here. Wanna ask if I want to buy or trade, where do I start? Basically, I need to find the original, first-gen, full-size Kanger Subtank, but that thing is discontinued and can't buy it anywhere any more.

Longer story; I'm now using the Kanger Subtank Plus, but it's 25mm in diameter, and it doesn't really fit on many mods that are made for 22mm tanks. The first-gen Subtank has a "beauty ring" I need. I also tried to find a third-party 25mm beauty ring but no one seems to be selling it any more.
