[quote=“amphigori”]Just a thought…
I have a few brass braclets and they tend to turn my skin green if I wear them too long. Dunno if the metal you’re being advised to use would do the same, but just be careful. As I imagine it’ll get really gross and sweaty under that mask I’d worry that’d contribute to the ‘greening’ of your skin.[/quote]
I thought that was copper that did that? Does brass do that too?
