Get some rips fit for royalty with the Monarch Gravity Bong from GRAV Labs! This gravity bong is made from quality borosilicate glass, crafted by glassblowers in the USA. The grommet is made from platinum cured silicone and ensures a tight seal with the outer chamber to prevent any smoke escaping. Decorative ribbed detailing can be seen all around the outer container, continued up the neck of the inner chamber. The dramatically arched shape of this section not only looks exquisite, but makes the bottle easier to lift out. Each gravity bong includes a 14mm male herb slide.
