Will these be primarily for the Provari, or other battery devices?
I have twelve IBTanked; seven 19mm and five 22mm. I must say I really like the 22mm not only for their looks (anodized aluminum in colors) but also for their added juice capacity (5ml vs 2ml). The 22mm tanks with a pro ring on a Provari is such a nice look. The below pics don't do the combo justice.
