watchesandwalletsI ordered a full shell cordovan (SC). It's quite thin yet sturdy. My chromexcel version is a bit thicker but much softer and flimsier. SC makes the wallet much firmer than cowhide. They managed to have thicker shell on the outside, and very thin shell for the card slots. Overall, it has the right thickness for comfortability and firmness for durability. Definitely an excellent purchase!
