Buy Authentic Direct From The Manufacturer. Created in collaboration with iconic Los Angeles rapper and entrepreneur B-Real, it is with the highest honor we introduce the Dr. Greenthumb's X Stündenglass Gravity Infuser. A sophisticated and elegantly designed 360° rotating device that generates kinetic motion activation via cascading water displacement, opposing airflow technology and the natural force of gravity. Fully customized throughout, constructed using the highest quality materials, including borosilicate glass globes and aircraft-grade anodized aluminum, the Dr. Greenthumb's X Stündenglass Gravity Infuser elicits an immersive experience while delivering smooth, consistent and vaporous draws. Designed for functional versatility, the Dr. Greenthumb's X Stündenglass Gravity Infuser is a complete set that includes an aluminum bowl kit and a glass bowl, but can also connect to any smoking or vaporization device with a 14mm male joint. Included is a 3-foot silicone hose that can be connected for direct draws, though a steady stream of smoke through the 45° adjustable mouthpiece affords the optionality for entirely contactless consumption.
