The Grav pocket bubbler is a versatile, portable water pipe. It can fit a 10mm herb bowl or a 10mm quartz banger for concentrate use, or even a pre-roll or blunt. The bubbler chamber adds a little water filtration while still keeping the piece nice and compact. The spherical bubbler stands sturdily on its flat bottom and fits very discreetly in your hand. The Grav spherical pocket bubbler does not come with accessories.
