These cards are great for cardistry! They come with a double backed card but the back side is colored differently. They do not come with a blank card but they are meant for cardistry so that is not a big deal. The advertisement card also looks cool at the bottom of the deck. They fan amazingly well although they do have borders which makes the fan look a little less impressive. The Sirius B V2 cards also have full sized pips which can cause them to be hard to read when fanned, but if you are skilled at fanning this is no real problem. The aces all are extra large but the ace of spades is still different than the rest of the aces. All of the cards have a interesting wavy pattern and it is most distinct on the face cards. The box is fairly plain with the same wavy design as the cards have, it fits the cards well, and has a little extra space so the cards slide easily in and out. Although the cards cut like a charm, they are not meant for card magic and are too stiff to work well for this purpose. All in all, these are amazing cards and are better than most decks. Well worth it for the price and I highly recommend them.
