Hi, I have several black lacker box set, THAT ARE DAMAGED. some just need touch up ?

Depends how bad the dings are.  If they're small, just try a touchup with a black Sharpie pen and don't look too hard.  Once you start with paint, you run into blobs and it becomes more obvious.  There are touchup kits for cars available with blob removers, but, not knowing what your box sets are made of, I couldn't say whether it might be damaged by the chemicals.  May be best to just put them in some nice plastic sleeves and prevent additional damage.  

Black sharpie ink is not actually black. It’s a dark blueish purple and sticks out like a sore thumb against a black background. 

The OP needs to learn how to write posts with meaningful titles. It’s hard to help someone who doesn’t bother.

I'm thinking they're like CD cases for his lp.'s and English is not his first language. At least I hope it's not.
