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.
