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.

Backpack for work laptop
Color: Navy/Tan
Purchased this backpack to store and carry my laptop for work. The zippers feel feel durable and the bottom of the backpack has padding to absorb some light impact.
