Hi - Im having a hard time finding Billow V2 Replacement Glass for the regular Tank and the Nano thats in stock and fast shipping. I know fasstech has them but I need the nano tank right away as Im out of spares and my wife has a crack in hers. Its not leaking bad but it is a tiny bit. Just a little moist on the tank. Anybody know where I can find them in stock with fast shipping? Thanks!
