Coach conditioner probably won't do much. I've noticed the purple iris duffles I see on ebay look scratched often. I think these two colors might be the worst. When I got my berry color block Willis, it was scratched. I used Blackrocks on it and it made it almost invisible. I haven't noticed it getting more scratches. Certain vintage bags get scratched every time I carry them.
Darn it! It's a really nice Red. I think you're right about the colors though. There was a Mink Duffle as well and it didn't have any scratches. The leather was the same as the Black one. I'd be willing to go for the Red and put the Blackrocks on it but I'd prefer to start with a bag with little to no scratches. The manager went in the back and she brought out what she thought was the best but she said they were all scratched. The one that had a small scratch had a stain on the other side. Thanks again!
