The most complete, compact wallet I've ever seen!!
This is the most complete, compact wallet I have ever seen, there is a space for everything, even coins. I ordered 2, one for me and one for him. Mine does not fit in my purse, it's 10 inches long. I'm debating, should I return mine or keep it. I've searched for one similar, less than 10 inches, and found nothing. He is so excited and happy, he has already filled his up. This is the only wallet one needs AND it's RFID blocking.

Loves this wallet
Color: Coffee6227, Material Type: Leather
Bought this wallet for my husband and he loves it. It’s softness, design, ease of use, perfect size and great value for the money. The magnet strength is perfect. Bought for Christmas and he’s still telling me how wonderful it is. Great product .

Quality Meets Functionality
Color: Black8017, Material Type: Leather
Very impressed with the quality material and functionality of this wallet, I had to buy a second one. (Coffee + Black). It opens and folds-out like a breeze in your hand and stays closed when not in use. The pop-up card holder mechanism works well too. The overall compact size makes up for the thickness of this wallet. It is thick. I wouldn’t recommend sitting on this one, but it’s small enough to keep in a front pocket while seated.
