Might not be the tease you thought it was. According to this link, Aristo Club was a trademark held by the Angel Playing Card Co Ltd in Japan from 2003 to 2012.
Confirmed by Matsui. According to their site:
"A quality card manufactured by Angel Cards of Japan, the most established card supplier in Asia."
Hmmm, that's very interesting as Hard Rock Casino London opened in Nov 2002. So these cards I have were probably ordered by the casino some time after opening (I believe the casino has been rebranded and is now G Casino but I am sure someone can verify this as it is many years since I last visited that London)
The cards I have I bought off eBay UK and they were all cello-wrapped. The seller said they were from Hard Rock London but the backs are just branded 'Hard Rock Casino' with no location. The boxes are just generic manufacturers' branded boxes. I believe there was also a HR casino in Manchester which has closed so the cards could have come from there as well (or there could have been a joint supply for both casinos).
At the time, I didn't know the brand or how good they felt but they were dirt-cheap for plastic cards, so I bought 6 decks. I now use them with my Hard Rock Albuquerque chips. It's good to know that they are connected to a superior brand, they certainly don't feel like a cheap plastic card (eg Royal).
