I played around with it. The quality is great, I think Tally-Ho paper stock is used for this deck.
I was told that the deck will be made available to his fans when he does his full evening show in Hong Kong this month.
However, I think the chance of these decks being available online for sale is very slim.
FYI, Lu Chen is not just famous magician, but more a super pop star kind of magician in greater China area, he has over 2 million fans following him on chinese version of Twitter.
For as little as 5000 decks, I bet his Hong Kong fans can take that much right on spot after his show.
If you don't live in Hong Kong then ... perhaps the only way to get them is wait for some of his fans resale them on eBay.
