I agree some chinese manufacturers skimp on the coloring in order to sell cheap. Uwell assured me the process was an identify PVC coating for the black. since the black does NOT bleed, id assume the rose gold won't bleed either..
Yeah... you might want to be careful with
assumptions--especially where Chinese manufacturers are concerned. Not trying to insult the Chinese people, but their manufacturing sector
does have a... shall we say "spotty?" history.
If that gold colouring is anodizing my (admittedly superficial) research indicates it
should be safe. But if it's just gold(-coloured) wash, plating or other coating: I'd be wary.
For what I'm looking for in a vape I doubt the Crown would work for me. But if it
is anodizing: I might pick one up, anyway, because it looks so cool
