Over the last few years Vapor bubblers (AKA oil rigs) have become the most common way to smoke legal concentrates like essential oils and wax. Vapor bubblers usually come a matching dome. We also sell sets that include a matching dabber, dish, and nail. Grateful J’s has products from a lot of artists like SLOP, JAG, Burtoni, Zach P, Grateful J, Down Neck, Hitman Glass, and so many more.
