Up for sale is my evolution top. Not used much as I found that I prefer to stir the load, so mostly used the T1 top instead. All parts required to convert your T1 or Revolution to an Evolution. I've got long short and Revolution mouthpieces for a couple bucks each if you want them too. I'm after $35 including postage within Australia $40 shipped to US, Canada, Europe, etc. shipping usually takes 1.5-2 weeks to/from the above places. I've cleaned this item by boiling followed by ISO Soak followed by another boiling, so international shipping is no problem (Thermovape products are known to be thoroughly cleanable). Thanks for your interest. Edit: Thanks mods and @SSVUN~YAH for your help with the images.
