Looks like a face shield for gas welding. Many here suggest she has hidden talents, perhaps brazing copper pipe is what they are implying.
I’m going to give it 4 guesses:
1] People can’t see her face and thus she can go out in public anonymously.
2] It protects her plastic surgery and bio injections from sun and rain and smog and volcanic dust.
3] She has it trademarked and intends to market it to make her condo payments after Sterling’s wife wins her lawsuit against her.
4] It serves also as a visor and will be called: “the V.isor”.
It’s just a dark grinding shield. Available at any hardware store.Very common item.
