The guy at the shop said it was an art piece. Set me back about $55. Feels sturdy as hell, and, yes, that spiral part is a big chamber. Haven't been able to try her out yet, but will let you know how she is when I do. Also, sorry about the closeup, phone camera, looks good in person, though.
I like it, the spirals look really cool. I have never really seen anything like it, or couldn't tell you an artist name or anything but who cares, its mega sweet! Let us know how it smokes, enjoy!
