Great wallet

Nice and plain
Color: Raven Crosshatch, Size: Standard
Great wallet, not flashy. No plastic screens inside, no coin pouch. Just a plain wallet that holds cards and cash. Standard size, fits in my pocket well. I cannot comment on the RFID, but my works badge does scan through the wallet.

Great product

Great basic wallet for my husband. This was a replacement for another Herschel Wallet he had for 10 years that was finally on it's last leg. Definitely durable and classic

Almost perfect.
Color: Navy, Size: Coin
Really nice wallet. I love Herschel quality. One issue with this specific wallet is the coin pocket on the inside. Cool idea it's just the snap for the pocket rubs on whatever the card is on the other side of the wallet. I had to move my license to a different spot before it was ruined.
