We know this about ghouls:

1: Ghouls can heal/regenerate

2: Ghouls cannot be harmed by human weapons/anything that isn't a Kagune/Kakuja/Ghoul body part

So then how come Uta can have tattoos and piercings if, by right, tattooing needles and metal earrings would not be able to pierce him? And how come the ink of the tattoos remains? I would have thought they could regenerate and get rid of the ink too?

Unless you're telling me that Uta's piercings, the tattoo needle used to tattoo him and the ink used were all made of kagune-like materials, or even a kagune/quinque itself?
