KORUMAKoruma RFID Blocking Biometric Passport Protector ID Theft Protection Travel Holiday Sleeve (BR 2 Pack)

Although it takes the least extra space, it's a bit too tight for my taste. You might damage the passport if you don't handle it carefully enough, which could happen quite often during a rush in the lines at boarding etc. where your hands are full with luggage and boarding pass / smartphone as well and the main idea about this product is to keep your passport outside for the smallest possible time frame.

This is basically an expensive piece of cardboard. A 48-pages passport is hard to fit and I had to glue one sleeve as it was coming apart.I haven't tested yet how well it shields the passport, but the RF blocking coating looks very thin.

I don't know if this works but it gives me peace of mind. It is just made of card and the passport is a tight snug fit, so you cannot use a cover with it.

The glue holding the metallized cardboard sleeve broke within a day. It's OK, but I suspect I will be looking for a different solution fairly quickly.

Great idea especially if it prevents id theft a little flimsy not sure if they will stand up to travel wear and tear for very long.

Passport fits issue free. Scanning is prevented when sleeve is on, which is the purpose of it.

A little tight fitting but excellent value for money. Feeling a lot safer whilst carrying it round.

I found the cover very thin & not easy to fit the passport into in the first place, but it served its purpose.
