Hi Roger,
My diana bag has been redyed. When I first got it, it has color coming off from the back, but the bag still feeling soft at the front. So I bought Leather Aniline Care - Kit-A3 to take out the color. Now my bag is very dull and rough. And it need some shine. Please see attached picture after Leather Aniline Care - Kit-A3 and dry. It still have some light blue residue when I had the last process.
