Bicycle Poker cards are popular used in the world. Those bicycle marked decks with the special big marks are loved by our customers, especially those who need to use the marked cards in a not so short distance. The big marks are special good and clear for people to see with infrared lenses or glasses. As you can see in the picture, the marks have its own sign for suits as well as numbers in the middle of the back.
Generally speaking, the number with no sign stands for SPADE (it's Spade J in the picture).

The number with a circle dot stands for CLUB (that in the picture is Club 2).
And the number with a vertical line stands for DIAMOND.
