Open box usually, but the point still stands.
This is a horrible deal and nobody should be paying anywhere NEAR £600 for one of these. I constantly buy iPhone 11s on eBay for £500-520 during eBay codes.
After getting in on the O2 deal last year this is simply terrible. Probably better to spend less and get the 2020 SE.
I have Mate 20 Pro and I can't fault it.
