The Traditional JBD Flower Bowl is designed using the Snodgrass "pushed-in" technique; this design allows the heat to rise up the inner walls of the bowl without the outer glass getting hot. allowing you to smoke more for longer periods of time. Whether you prefer a snappy one-hit, or packing the bowl to the brim, the JBD bowl will deliver the optimal smoking experience.
Why does JBD use Rubber O-Rings? With functional glass, a perfect seal is everything. While "Glass on Glass" joints are made to fit the best they can, they just don't have the flexibility rubber has to create the ideal seal.
