Query: Better than Kems

First let me say that we used Kem cards in our club exclusively, however, the last few decks were so bad that we decided to try Copags. Lucky for us, as these cards are much better. No problems with the cards. No defects (Kem had 4 of 4 decks bad). If you play regularly you need to use these cards. They are washable, almost impossible to ruin (with normal use), and they feel brand new for a long, long, long time. Once you use these cards you will never go back to regular decks. If you only play once in a while, then the cost of the cards may not be justified, but the feel, slide, etc., is so far superior to regular decks that you will be glad you bought them.
