The Pulse Glass "Slim Jim" is the epitome of a scientific rig. In just 12", it's able to fit two of Pulse's most popular perculators. Both percs work together flawlessly to create a remarkably smooth airflow. The Wig Wag and Red Elvis trim along the base and mouthpiece adds a nice touch of color and style. The "Slim Jim" instantly became a favorite among Pulse Heads.
