So last week I received my "black" Costa Rican Willis with nickel hardware from Mercari and it turned out to be navy blue. Again. I have now bought two "black" Willises that turned out to be navy blue. The first one I decided to keep because it was in great shape and I decided I liked the color after all. The second one was a major disappointment and I didn't want to keep it. However, I bought it off of Mercari and I didn't even open the box within the first 3 days....for reasons. Just reasons, we'll keep it at that. Long story short, my fault but I'm now stuck with the bag. The bad news is that when I finally did open the box, I discovered the back pocket was covered in white colored mold. In a moment of exhaustion and irritation I filled the entire purse with straight white distilled vinegar and let it sit overnight. I rinsed, soaped, and soaked again this morning and now the bag is drying. My question is, do you guys think the white vinegar killed the mold? Would you feel comfortable carrying the bag or at this point should I just scrap the bag and harvest the lovely nickel hardware from it?
