The T.V.L. 21700 Jmax is beautiful to look at and even better to operate. Not only is T.V.L.’s machining second to none and the threading on this mod buttery smooth, but this one in particular is #2 off the line with the serial number #002 shown right on the top. The power, which is supplied by a single 21700 battery, is immense. This is a mod for those who want their hit now and won’t take no for an answer.
