Jil Sander Brown Cracked Leather Long Wallet W/Gunmetal Hardware

Well used Jil Sander Long Wallet. It has the cracked leather effect that they like to use on their wallets. It has some discoloration on the front that I have pictured and I don’t know what it is. I did condition the outside of the wallet and tried to clean it and it did not remove. The wallet is well used and priced that way. Still has a lot of usability and no rips or tears that I noticed. Measurements on the photos as well. Thanks for looking!
