I did ask! They have now received the whole Ophidia collection but not the clutch and they didn’t know about it. Maybe it is only released in the US? Because they do that, don’t they at Gucci, release some stuff only regionally to keep things more interesting for us...
Yes, even besides official exclusives and ltd eds there are plenty of things that are only available in one territory. I had to ask a friend of a friend to bring back my dark green hat (only pale green, red and black was available here) and I've missed out on a couple of scarves too.
If it's for that reason sometimes Farfetch can help (you can ask for a personal shopper if you can't see it on their website) and I've also found a 'not available in Europe' scarf through NAP UK. So check all the third party stockists first.
