The V12 mini twisty blunt is a lot like it's bigger cousin, but just a little larger than a standard glass bat (a little over 3 inches). It has a glass and metal mouthpiece that can be swapped out with any push in 510 size mouth tip. The twist screw has a smoother look and feel than the first generations of twistys. It has a built in filter and storage cap so you can easily load it up and take it with you for all day use. Comes with a Poker/Cleaner tool and a spare o-ring for the main seal.
