Version 2 is 22mm in diameter, and can be used either as a tank or a dripper with ease. V2 Features 4ML juice capacity, 316 grade SS steel construction, adjustable airflow option for both tank and drip mode & has a hybrid mounting option. Also includes spare O-rings, Hybrid adaptor, screws and the usual blue screwdriver.
In great condition, perfect working order. I liked it so much that I ordered the authentic version from VaporKings.
Asking $12.50 shipped. Thanks for looking!
