It's a Keychron K8 Pro with the vintage keycaps... but in French Azerty mac layout, and that's the real deal ahaha

They are the retro keycaps from Keychron (the only one I could find with an ISO Mac French azerty layout, actually). They're meant to look like old school Apple keyboards :)

I did't do anything particular, just went on the subreddit page, pressed new post and chose "image". I'm on iPhone btw if that makes any difference
