The Worked Bubble Bongs from Boro Farm Glass. The bubble shaped bong features a worked wig wag downstem, a skinny neck mouthpiece with a flared lip for splash-less bong tokes. A 4-slit diffuser downstem provides exceptional percolation and maximum volume within the water chamber. The size and function of this water pipe make it a perfect daily driver for pot smokers and includes a 14mm 1-hole flower side. Boro Farm Glass bongs and dab rigs are handblown in Portland, Oregon from quality American borosilicate glass.
