Grav Labs and Stephen Pierce present a perfectly portable dab rig amplified by the combined genius of these Austin-based glass masters. Comfortable in-hand, this scientific glass water pipe stands 5.5 inches tall with a wide fat can chamber. The hydrodynamic-powered interior is fitted with diffused umbrella perc for smooth, easy rips of crisp and clean concentrate vapor. The refreshing mini rig flaunts a 14mm, 90-degree male joint made with premium American borosilicate quality. It’s paired with an angle cut dome for a full range of motion with the dabber. Easily load up the heated nail – that’s flawlessly cut for an excellent carb cap seal – as you give it a rip through a comfortably arched neck and flared mouthpiece. It’s no surprise the meeting of these great glass minds has created an exquisitely efficient, impressive piece of science-inspired art. The Grav Labs x SPG Umbrella Perc Vapor Rig is an essential addition to every concentrate collection.
