We love these cards. The card back is textured, they're not too slick. They're thick enough, but not too thick. They have a crisp sound to them when shuffling, pitch well, and are very durable. Dal Negro cards are in play at the most prestigious casinos in the world including the Casino de Monte Carlo in Monaco.
There are a bazillion plastic playing card manufacturers and endless designs and configurations. We like jumbo sized pips and poker size cards. These are about the same thickness as KEM cards, slighly thicker than Copag, but not as thick as Faded Spade cards.
