Nice But Overpaid
Color: Black Embossed
Very happy about the purchase. The style is great, size is perfect, and the leather is really nice. When I unpacked it, the MSRP ticket was inside showing the cost of $125, but I paid $150. Not so happy about that part.

Nice
I love it. It's a nice slim wallet. Nothing special, but looks really nice, works well. I've been using it for a month with no problems. It's nicely lined, seemingly well made, etc. I got a good price on it, so I'm happy.

Cards don’t fit tight
Color: Black Embossed
My credit cards fall out. Needed a more secure alternative— still stayed with Tumi though.
