... Playing cards ... :)

Initially, even - like all other playing cards also - quite smooth and accurate pre-sorted cards. After a few rounds, these are quite handy and mixed well ...;)
Durability will not be much different than other playing cards also - after frequent and intense use some cards (corners) will be bent to look splicing and just like playing cards)

The packaging, the game card stock, something ... "getting used to": the depositors of cardboard that holds the two card deck is not connected to the outer carton, so that is taken at each removal of depositors. However, a little glue creates the remedy :)

Who are the cards too smooth, which can pull it before using so several times on the (wooden) table top. Or even buy a used card game ...
