M+Mpw LoYen Long Wallet

Lo Yen is the definite article for the Japanese currency, the yen.
This wallet has plenty of room, eliminating the drawback of long wallets, which tend to expand from the center and lose their shape when filled with various items.
It has a large capacity that can hold 45 coins and coins in denominations of 500 yen, 100 yen, 10 yen, 5 yen, and 1 yen, so about 10 of each.
It is relatively compact when not much is put in, but if you put a lot in it will expand along its thickness, giving it the flexibility to do so.
