So for those of you who live in medicinal states and can use reopens with prepackaged solvent less oil cartridges here's something I just thought about trying tonight.... This bubbler has a 14mm joint so all I did was touch my reopen unit to the joint and it fits PERFECTLY. Bubbler hits of vapid solvent less hash oil....I've gotta be one of the first!!! Some Og Kush Solventless hash oil...mmmmmmmm [ame=http://www.youtube.com/watch?v=avTyF8Fzjm8]Rempen + Bubbler milks - YouTube[/ame]
