According to the person who sold me these, these bottles were actually used to serve Gin to guests at the Assassin's Creed Syndicate London Launch Party. These were not given out to guests. Instead, all the bottles were apparently destroyed after the party, but the seller managed to grab a few; 3 pairs he said. (I have 2 sets here).
So, really rare stuff! I think I got a bit too excited and bought 2 sets and paid quite a bit. Might have to sell away 1 set if the price is right.
These were given out at the party, to exchange for drinks I believe.. Seller was nice enough to give me a few of these together with the bottles.
Very special stuff, adding to the AC Syndicate Collection. Definitely more coming in the coming weeks!
