I am used to standard Copag 310 decks. I have heard these thick cards are not favoured for cardistry, which could explain why the new slim-line cards have been made.

I think Copag 310s are fine as they are. Despite being thick, they handle beautifully, with a soft buttery feel, and they flex well, so are great for double lifts.

I was still interested to try the new slim version, which is meant to be several cards thinner. And it is. The packet itself is visibly smaller, otherwise looks the same.

The beautiful texture and feel of the originals has gone, replaced with ordinary feel. Not a great problem, except the los of the great feel of the originals. But the problem I had was dribbling the cards, after one face-down dribble, they had warped. Dribbling face up was difficult.

After a minute's use, I put the deck in the fridge, and took it out hours later. The cards were then closer to being flat, but after one more face down dribble they were warped again. Rinse, lather, repeat, every time the same effect.

I have tried buckling the deck hard, but it always ends up bowed the original way.

I would rank these cards as 1, just good enough for a self-working trick. I give them 2 here as it could be argued that the thinner cards are better stock, just more volatile, and just don't work in my climate (oz). But since I have no trouble with the old standard cards here, I can't be more positive with the review.

My rating is a personal experience only. If you live in a different climate or get a better copy, they may be fine for you. Would suggest you ignore my rating, which is arbitrary, and try the deck for yourself... especially if you are used to the previous model Copags.

I'm not sure why the bad reviews but I thought I would offer a contrasting experience. I have been using and abusing my copag 310 slimlines for a good few days now. They faro well, they shuffle well. The edges are soft and supple right out of the box. They make pinkie counting easier (subjective) than regular bicycle stock cards. They have stayed relatively warp-free despite a lot of shuffling. Also I should add they are much less affected by humidity than anything by USPCC in terms of warping.

The con is they don't fan as easily anymore and clump a bit, but that's true of any cards I have used after a while. When they were new they fanned beautifully. It might be my technique too as I am not great at fanning at the best of times.

This isn't a plus or a minus but they have a very different feel than USPCC cards. Almost leathery. It's hard to describe but is definitely interesting.

Overall when you consider the price definitely a great deck.

I was very disappointed when I received the cards.I thought it was the best cards. but not because the fan doesn’t work, faro shuffle doesn’t work, and the color, pipes and figures are not nice. You can also see the dark glue throughout the back and face layers.
