Love the wallet
Brought this for my boyfriend for Father’s Day he loves it still has it and is very very old is a year old and it still looks new so good quality on the wallet and worth the price it was sold for. I don’t think I would find anything cheap cheaper.

Good gift
I got this as a gift for My boyfriend. He is a mechanic that means he’s always working on trucks. It’s always in his pocket and has been through a lot and it’s still holding up.
