This 16" straight tube, from Grav Labs, is one solid piece. Made from super thick glass, with a nice and wide base, this pipe is built to last. The inverted restriction works as an ice catcher to cool your smoke while inhaling.It features a honeycomb disc percolator, with an option for a colored glass base and mouthpiece that matches. The stemless design is functional, good-looking, and easy to clean. The bong features a random Grav Labs decal down the front of the pipe and includes a 14mm Grav funnel bowl. This water pipe is designed and distributed by Grav Labs in Austin, TX. Keep in mind, the logo color may vary from the photo above.
