Those actually look like the why 8.1 in matte black with BIP lenses. I’m pretty sure I had a bag that looked like that too from an Oakley from that time period. The case looks incredibly fake though. Maybe you could ask the seller if they got that case with the glasses, if they say yes then you know for sure they are fake (I cannot remember if the why series came with their own case).
Arm says why, sku on the other arm is wrongPicture shows Why 8 printed on the frame. Case is fake AF
