SERMAN BRANDS Slim RFID Blocking Leather Wallet for Men - Minimalist Front Pocket Bifold Wallet for Travel & Everyday Use - Thin & Lightweight Design for Cards & Cash

I was looking for a new wallet for a trip I had booked. I wanted it to fulfill these criteria:- Slim- Minimalist- RFID blocking- Capacity for multiple credit cards- Capacity for foreign bank notesThe first four were quite easy to find in most wallets listed here on Amazon, but I had a hard time finding one that could fulfil that last requirement. They were usually just big enough to accommodate US dollar bills - which are all uniform in size irrespective of denomination. Euros increase in size as their denominations grow, so they would not fit well in any of these wallets. One of the questions on this particular wallet piqued my interest as it asked if it could handle Euros and I, like the original answerer, can confirm that it can handle them... and pound sterling banknotes too!My 3rd and 4th picture give a sense of the difference in dimensions between a few kinds of banknotes. In general, US dollar bills are larger widthwise than both pound sterling and euro banknotes but tend to be smaller height wise (where I am defining width as the longest edge and height as the shorter edge). For those interested, here is a list of the exact dimensions (W x H) of the banknotes in the pictures:- £10 banknote: 132 mm × 69 mm- £20 banknote: 139 mm x 73 mm- $5 bill: 156 mm x 66.3 mm- €20 banknote: 133 mm x 72 mm- €5 banknote: 120 mm x 62 mmI had no issues inserting any of the banknotes height wise (i.e., the bill is folded in half and inserted along the longest side) as you can see in the 5th and 6th pictures. However, if you were to try to insert a bill with a height greater than about 74 mm (as is the case with euro banknotes €50 and greater in value and £50 banknotes) you would likely end up crushing the edges slightly with the fold of the wallet. This can mostly be remedied by rotating the larger banknotes and inserting them widthwise (pictures 7 and 8), the only exceptions being the US dollar and euro banknotes €200 in value and over which, even when folded in half, still stick out over 74 mm (pictures 9 and 10).Tl;dr This is a quality wallet that has survived an entire trip across Europe with minimal wear and tear, all while keeping my cards and cash safe. It can easily fit most kinds of cash - including any denomination of US dollar or pound sterling - but will have trouble fitting €200 and €500 banknotes (not like those are very common anyway).If I were to make any suggestions for improvement it would be to perhaps add a zipper to one of the cash pockets (if that is possible) so that the wallet could also safely hold some change. I found loose change increasingly difficult to manage on my travels, so I think a coin compartment would be quite convenient.
