Yes, these are Bicyle cards. Yes, the marks are easy to read. No, it is not likely anyone will
suspect you of using a marked deck or will see the markings. Yes, this is a very good marked deck of
cards.
Nontheless, it is still a deck of cards. This means that it's going to wear out if
you use it regularly. Then you'll have to buy another one. At 19.95 a pop, these decks aren't cheap
(you could by 8 decks of regular cards from penguinmagic for the same price). Take that into
consideration before buying.
