A pleasantly light and very well made pipe with a slim line. The delicate proportions are made possible by a 6mm filter shank. With the SIX, Vauen is celebrating a small revival: after years of building 9mm pipes, a smaller drilling is finally available again. And all of this in time for the 100th anniversary of the patenting of Dr. Perl activated carbon filter in 1921. Enjoy the SIX with the new 6mm Dr. Perl activated carbon filters.
