This 10 pack of GRAV Glass Blunts keeps you stocked with enough 4" high grade borosilicate glass blunts to keep the sessions going all year. A pinched straw mouthpiece blocks ash for cleaner hits. During the session, the mouthpiece is gradually pushed deeper into the outer sleeve, ashing the GRAV Glass Blunt and exposing fresh dry herb. Smoke is sifted and cooled as it travels through the airpath. The GRAV Glass Blunt delivers the portability of a blunt with the smooth hits of a glass pipe.
