My Kaneki Nendoroid had some of the paint on the face smudged off during a move. If it was a small smudge I'd just ignored it but it looks pretty bad. I initially thought it was ink or something and tried to wash it off before I realized it was the skin tone that got rubbed off. I only have a few nendoroids and am new to the community. Is there a resource to get skin tone paints to repair this? Or something similar?

I thought about replacing him but apparently they didn't make many of them so it's expensive to replace.
