Double Percolator

Built with two chambers and two percolators, this dab rig is designed to provide the user with the coolest and smoothest hit possible. Filtering the vapor not once but twice, the bottom chamber’s inline diffuser forces the vapor to increase in surface area. Due to the suction, this vapor then passes through to the next chamber where the filtration process reoccurs with the JM Flow signature crystal ball perc. The eventual outcome is a cool, clean smoking experience for the user.

Made in the USA

100% made in America, this elegantly clear dab rig is designed and made in California from the finest borosilicate glass. JM Flow Sci Glass decorate the chamber wall with their sandblasted logo to illustrate which studio this prestigious piece was crafted in.
