T'is a Protogen mask, and i too would like to acquire one myself

Looks like you'll either have to make it yourself or find someone who can make it for you, neither option is particularly easy nor cheap

It's a protogen (original species by Koinu)! Uhhh... this one the visor I bought from someone but tinted myself, headpiece models also bought but i 3d printed, everything else done by me. Some people are willing to make them as commissions or premades though (however a lot of people make their own)!
