Grav Labs - Direct Inject Nano 8-arm Perc Vapor Bong

This Straight Natural Nano 8-arm Perc bong from Grav Labs is made in the USA (Austin, Texas) using only high grade borosilicate glass. With a stable round foot, 10mm micro joint and flared mouthpiece, this slender, 38mm-wide Grav Labs tube is solid, hefty and comfortable to use. The 8-arm tree perc is small yet powerful enough to deliver cooled, smooth hits. Designed for smoking concentrates, this piece has a 10mm male joint and comes complete with a 10mm vapor dome and 10mm glass concentrate nail. The Grav Labs Nano decal is applied on the tube in black, blue, red, etched or green, as available.
