Promising review: "Best travel wallet ever! I've been wanting it for a while and I had two trips where I regretted not buying this. For my last trip I decided to give it a try and bought it. It's amazing! The passport fits great, my green card has a special place, my credit cards feel safe, the phone chip fits great, and I used the small slot in from of the money compartment for my room key. It's portable, fits a pen, and it's a great asset in general. Don't hesitate if you're thinking of buying it!" —Rosangela Rodriguez
