I definitely am not a card expert but sure am a card enthusiast. Bought a few cards recently from Amazon and would like to leave my feedback. I bought Fournier EPT plastic cards, Copag plastic cards, KEM Arrow plastic cards and Bicycle Prestige cards. Off all of them i like the Fournier's best. They have a substantial feel, very thick and you can feel the quality. Dont know why KEM's are considered the best but these, to me atleast, are better. The KEM's are very thin in comparison. Also the cards are slippery but not on your hands. They have a very rough texture so holding them is very comfortable but the cards glide over each other effortlessly. These are made in Spain. The KEM's i found are similar in thickness and texture to the Copag's. The Copag's have the best packaging, very neat. They are made in Brazil. The Bicycle Prestige cards are also made in Spain, most likely by Fournier. They are similar to the Fournier EPT in touch and feel but not as thick.I think since Fournier is a European company and not many people in the US know about them they are not aware of the quality.To me Fournier's are better then KEM's. To others i can say this much, even if they are not better than KEM's they are atleast equal !!!!
