Bought Three of These!
Bought three of these wallets as gifts. Everyone liked their wallet. Great construction with plenty of pockets for cards and cash. Nice looking too.

Great gift
It’s really hard to find a wallet with a mesh ID window. This one looks great and fits very well in the back pocket.

Herschel is seriously the Best!
Color: Black Tonal
Got this for my teenage son & it was the perfect size for him. He didn’t want a bulky wallet, just something simple to carry his school ID, cash and his debit card. Herschel has amazing quality products, definitely can’t go wrong with them! Worth the price for sure :)

Nice and thin
Color: Black Tonal
Slim wallet. Made for a minimalist type of person. Ideally for only about five cards and some cash anything more the wallet will start to bulge.
