The 4.0 Glass E4 concentrate rig combines precision-engineered quartz with a 24mm outer diameter design, featuring a 4-hole airflow system that enhances vapor diffusion through larger glass pieces. Made in the USA by Eric Ross, this handpiece requires a specific custom coil (sold separately) and includes one durable cotter pin for secure operation. The quartz construction and tourbillon functionality work together to preserve the full flavor profile of your concentrates during each session.
