I don't carry my passport around daily when travelling so I have no use for a bulky case that adds the content of my normal wallet. Hands down, what sold me was the fact that there wasn't just a pocket for the vaccination record, but a snug windowed spot that allows me to easily display it when asked. Personally, I tucked the separate, also-included sleeve inside this slot so I could pull it out and carry it solo as needed.
Of course, at a $10 price point (for both!), it's not real leather, but this rose gold one didn't have the tell-tale sheen and texture that some faux products do. If this shade isn't for you, there are nine total options. You just may soon find yourself choosing colours for your whole family like I did, too.
