These pipes are all hand made in Rosewood carved by a true artist. They take 510 XL cartomizers and are completely maintenance free. They take different batteries from 18350, 16340 and 18500. Tehy contain very few moving parts and are fully manual. They produce a fabulous vapor and are really nice to use. The feeling of the highly polished rosewood aginst the palm of your hand and the slightly bend stem, makes it the ultimate delight - at least to me. I also have several VV mods as well as countless genuine eGo both standard 510 and Tank fitted, and I've used all possible cartomizers, clearomizers, tank cartos, tank clearomizers, siam tank-mods, you name it, I did it. But now I simply can't stop using my Jazz ePipe from Romaniac. I haven't made so many pics of my pipes yet but I have one or two to share.
