This is a special DUFv3, there has been a few subtle changes from the v2 such as the mouthpiece, and uptakes, as well as this being a show piece . It is made with Pdx, northstar and Greasy glass tubing. Has a 10mm faceted joint with a 3 hole perc, as well as a faceted opal attachment, with an Opal on the bottom. It is about 6-7” tall and it shreds!
