Human Grade Carb Caps

Our Human Grade Carb Caps provide controlled directional airflow for compatible bangers, helping retain heat and improve vapor movement during concentrate sessions. Choose between the Bubble Spinner Cap, a compact borosilicate glass design engineered to create spinning airflow for use with terp pearls, or the Spinner 3 Cap for an alternative spinner-style setup. The Bubble Spinner measures approximately 1.6" x 0.8" and is made from heat-resistant borosilicate glass.
