3.Size:100 x 75 mm
Each page has a divider that sits nicely between the two cards. This means that when you use the thumb hole to remove one card, you are not also removing the other card sitting behind it. Each page is 3 ply.
I would not recommend using this as a primary wallet, unless, all you carry is cards. It will not hold change, nor does it have a currency pocket. It seems well made, no problems to report.
It may fit into other larger wallets that are not made of stiffer construction. It sits nicely in a small side pocket in purse and is still easy to grab and use. I would definitely recommend it!
