leather question

[findmewdw]

I have a leather couch and chair that is only 4 years old. It is badly worn/stained where your knees are in a few spots. Has anybody used a leather recoloring product that works well? The leather magic, which has a website, is one that I am tempted to try. The furniture is in good condition except for the worn spots. I would love a pen that could be used in those small spots, but can't find one. I know they make them for wood touch ups and I use them often on my wooden furniture. Any advice would be appreciated.
