So I got my Michael Kors patent leather bag in red a few years back. A year ago, the red color started staining the items inside my bag like my white wallet or the papers inside. Then when I wore my white winter jacket, it just stained the part where I put my bag on (it's not completely red but it shows a hint of red). I'm getting really tired of my bag staining my things. Is there something I should be doing to seal the color on my leather? I'm not sure what I should do or if it's just my bag.
