This thing seems to have all the rubbery nubs & textures as well as a brush that wasn't damaging to the soft nubuck leather of my handbag and was fairly effective at removing stain.

As happens quite often, the blue dye from my jeans rubbed off into the leather of my bag. As it was a very expensive bag AND I love it, I didn't want to just toss it. I figured I would give this a whirl.

It worked fairly well. It took a little bit of time and the dye didn't come out completely, but it definitely looks much better and it doesn't appear to have damaged the texture of the nubuck leather.
