Yup, direct from that actual link, it appears to be a direct Amazon link, not a third-party, the speed of turnaround was bloody amazing, it was fairly late when I pressed the button, and it was something like 9-10 the next morning when they turned up!
I can’t see anything that indicates they might be a knock-off, all the registration paperwork, the spare nose pads are present, and everything on the frames is crisp and detailed, the fine print showing model number is crisp and sharp,
I’ve just ordered the Revant photoreactive orange/grey lenses for them, weather’s changeable enough at the moment I think I’ll get a lot of use out of them!
