This is the 18.8mm Spherical GG wand made for the Spherical GG heater cover.
You can make it hands free by ordering the hands free attachment found on the Vaporizer Parts drop down then 7th Floor Parts! The spherical ground glass connection is made to be an even controlled heat distribution by giving the user a full range of motion with the wand while still having the air-tight seal of the ground glass connection. While giving you a larger bowl compared to the traditional ground glass set-up.
