It’s hard to design a functional passport wallet. You need to be able to remove and re-insert your travel document quickly and easily when you present it at security, immigration control or hotel check-in. That’s where the sleeve design is perfect, and the pockets between the leather and wool felt let you store and access a couple of credit cards and some folded banknotes, too.
This is my second purchase from Harper London - I also have a zipped laptop sleeve/document folio - and was once again impressed by the product and service. Well-stitched rich brown leather with wool felt as a cushion and to absorb any humidity. Ordered Monday morning and delivered Wednesday afternoon to North America. You pay a little bit more, but you definitely get what you pay for.
