Yeah Glass99 as the cheapest price on the teal version, but they also have a good price on the purple version, and they offer a purple version with a fountain honeycomb instead of ratchet slits... And Glass99 are very fast to ship, responsive via messages, along with good quality glass work! Just sayin again..
DGC_glass also sell that tornado piece as I posted it here a while ago, they ship faster than any other seller on DHgate in all my experience, 9 days to California, and some of the thickest glass I've seen as well!
