This two in one glass bong functions as a honeycomb bong for both herbs and oils. It features two honeycomb percolators with a turbine/ tornado disc sandwiched between them. This bong has a height and diameter of 440 mm and 50 mm respectively. This item also features interchangeable bowls allowing them to be used for both oils and herb mixtures. With a glass thickness of 5 mm, this piece of equipment is strong and extremely sturdy which enhances the expectancy of its usage. The subtlety of this Grace Glace beauty is enhanced by the hits of dark blue throughout its clear body.
