Hi,
I have several hydratubes. At the moment I can only find three of them. Two are unused, one of the two came from Vapexhale's Indiegogo campaign and is a huge Swagger hydratube. I also have a working OG Cloud and two Evo's.
Let me know if you're interested and I'm sure we can work something out.
