One, two, three, FOUR, I declare a POST HOLE WAR! The Brass Raiju by Vape Head Origins has a split positive center post with two postholes for crazy easy dual/quad+ builds, for a total of four holes and three posts. Similar to Vape Head Origins' Helios, but 22mm for a sleek look on your favorite mod. (Looks super topped with the 2puffs Regal in brass as well :)) Come up your build at The Vaping Buddha today! 615 W Orange Ave South San Francisco CA
