KAPTAIN SUNSHINE × PORTER Mini Wallet

This is a Captain Sunshine x Porter leather wallet, the Round Wallet, in brown.

I purchased it at a store several years ago.
I've used it a few times, but only when using a mini bag, so the frequency of use is low. I put it back in its box after each use and stored it.
There is one stain (please refer to the 3rd and 4th images).
Other than that, I believe it is in relatively clean condition.
The box has some dirt.

Thank you for looking.
