The design of the Twisty glass blunt includes a half-inch space between the top of the glass and the end of the screw. This crucial design element creates a long lasting cherry, or the hot burning end of your herb. The cherry lasts long enough for a circle of four friends to all puff-puff-pass. Then, just rotate the screw forward to load a new fresh bowl of green and start puffing all over again. Our Twisty glass blunt will get you and your friends faded in no time, with minimal packing/grinding/loading. You can purchase a Twisty glass blunt here.
