Got this for my dad for Xmas. He’s the pickiest person ever with wallets. He’s had the same one since I was in elementary school. He likes the trifold heavy duty wallets so I thought I’d give this a try and he has been using it ever since! He really likes the quality and durability and trifold in this wallet. Super secure and the leather is nice. Lots of card capacity and isn’t too thick

Heavy duty wallet.

Color: Black (Trifold)

Wow, this wallet is heavy duty thick leather with fantastic stitching. Will last a long time, very durable for a work wallet. The leather is smooth and fits well in the back pocket. A wallet for a man, not a boy.
