Black Leaf Ribbed Summit Glass Bong Bowl 18.8mm

The Black Leaf Ribbed Summit is a clear borosilicate glass bowl designed for bongs and water pipes with an 18.8mm female joint. Its distinctive stepped, ribbed chamber gives it a more substantial profile than a standard smooth bowl, while the Black Leaf logo adds a recognisable branded finish.

The bowl features a wide 10mm intake opening for strong airflow and a small side glass stop that provides extra grip and helps prevent rolling on flat surfaces. It works well as a replacement or spare bowl for compatible 18.8mm glass setups.
