Indeed, this reference refers to the cardboard used for the package, because it offers a very flattering peachskin appearance and a velvety, extremely qualitative touch. Moreover, and this does not spoil anything, this cardboard comes from eco-managed, therefore renewable, forests.
The whole package is highlighted by golden reliefs of the most beautiful effect. The front panel follows the design of the ace of spades, hand-drawn and very successful, and is marked "Black Edition" or "White Edition" (as here). The back of the deck is the back of the cards, which is simply superb.
