All Kulture locations have received Sheldon Black Smokeware's new 5 arms. Sheldon has already put out a 7 arm removable and a 6 arm fixed stem. I think the addition of the 5 arm was a good choice. Customer concerns of the everything being over sized on the SB 7 arms and the 6 armed stem being fixed were taken into consideration and addressed in the creation of the 5 arms. The joint on the 5 is 29mm in comparison to the 44mm one on the 7. The arms aren't diffused on the straight 5's either. Could this be a nod to Tony at Good Stash? As he says why would you want a stem that's cut halfway through? Or did he say half broken? LOL My guess is that cutting the glass at an angle is difficult. It doesn't matter anyway, they still rip! These pipes go perfectly with the new SB 5 arm ash catchers, which have removable arms as well.
