I'm a bit disappointed in COPAG. I watched my player shuffle the deck and the Kc corner bent. There is no damage to the card, etc., the corner just bent as he shuffled. I sent them the card, 4 aces, and the warranty card. They returned my 4 aces, my Kc, and a new Kc, but said there was no defect. So, they replaced the card, but not the entire deck. I did not look at the new Kc closely, because I don't want to know if it looks different than the rest of the deck. But I've had this deck in play for 5 years.
I might write them and tell them I'm not happy, but honestly I don't want another deck, or anything from them. I'm moving on from COPAGs. A tad slippery.
