Do you crave glass cooled vapour while using a VapCap? Your wish has been granted in the form of the Hula Stem. The small (60 mm) Hula Stem works in combination with a DynaVap stainless steel or titanium tip adding the purity of high-quality glass to the flame powered DynaVap experience. Indentations on the inside of the tube add an extra surface area which the vapour has to pass through. This cools the vapour and results in a very smooth vaping experience.
