## What I Like
The fabric is excellent. It feels great in your hand and feels durable. It's got a lot of potential for a slim wallet.
The magnets are strong and add stability and a pleasing *snap* on closing or opening. It feels secure.
Capacity is not huge, but I'm a strong advocate for putting your less (or less likely) used cards in your bag - not your pocket - and pitching receipts and other junk you don't need. And when closed it holds your passport, cards, and pen with just enough give so that nothing is tight.
I love that it's got space for a pen. My other passport wallet doesn't. And I think it's good that it's got room for some cash, but I didn't check if it's long enough for paper Euros (would need to be ~160mm?).
## What Could Be Improved
I'd have made the wallet taller in order to keep the magnets in the seems outside of the footprint of the passport. As it is, the magnets - which are not thick, but every millimeter counts - add bulk because they sit on top of the passport. And that bulk is at the edges where it matters most. The magnets also worry me - magstripes are on the way out, but you'd probably damage yours if it swiped past these powerful little things.
The most important dimension on a wallet in your pocket is the depth (thickness) and the second most important is the width, because that's the dimension that follows the curve of your leg. So you can let a wallet like this be a bit taller to optimize for depth.
Speaking of width, the seems seam a bit generous or even unnecessary on the outer edges, adding precious millimeters where it matters second most.
The RFID blocking material is too thick (too much plastic). On this wallet, the passport (or notebook) is going to provide all the rigidity you need, and the magnets provide additional stability. I suspect a much thinner plastic would provide sufficient stability to the aluminum layer inside.
The AirTag pocket would be greatly improved if it could be moved to the other side of the RFID blocking material. That material being too rigid, combined with the thickness of the AirTag makes not only for a bulge, which could be tolerated in its strategic position, but an ungainly crinkle, sandwiched between two large flat semi-rigid layers. It bothered me at my Pebblebee Tag's 4.5 mm - I think it would drive me crazy at the AirTag's 8 mm. (The Pebblebee Card is a better option in a wallet, at 2.8 mm.) I'm not sure how to design the AirTag pocket to be outside the RFID blocking layer, but that layer is also going to attenuate the signal from the AirTag a bit, reducing range or decreasing battery life, depending on how it works. I might argue that there doesn't need to be an RFID blocking layer there at all, because most passports have their own layer, but then some don't, and notebooks don't.
And finally, I'm not a big fan of layering / dividing cards. It adds minimal bulk with the die cut and material used, but any bulk is bulk to me.
## Conclusion
I like it, but I don't love it. Some changes could make it better enough that I'd carry it on an international trip, but I found myself moving it to my bag when it got too cumbersome (and then moving it back to my pocket to give it a fair chance).
So my favorite passport wallet is still my (discontinued) spinnaker sailcloth Allett Passport Wallet. I haven't tried their current passport wallet yet - it looks like the design has changed a lot and they don't use the crinkly but thinner sailcloth anymore.
