If you want your passport to be protected and look cool then how about a passport cover that looks like a really thin digital camera.
The passport cover has the front and back printed as a camera and that is just fun.
Inside there you find room for your passport and other travel things like you frequent fly card.
Now your passport will be protected from harm and it will be super easy to find yours in the stack of passports if you travel with the family.
So stop having your passport bare because this passport holder just looks way to cool for that.
