Review on Leather Card Holder Modern Carry Men's Accessories by Steven Saric

Maybe I don't know what "Wallet Sleeve" is because this product does not replace the card holder in the front pocket of your pants. There is only one slot and it can hold around 5-6 cards. So I can't use it as I need space for at least 8 different card types. 10 would be better. However, if that is what you are looking for, the quality of the leather is very good and the price is reasonable.
