Closet Purse Organizer Fairly New Leather Purse But Weird Black Marks Appeared?

Fairly new leather purse but weird Black Marks appeared? - closet purse organizer

I bought this red clutch (leather) wallet 2 years ago for my birthday Goody. J has a diamond in the middle. I wore about 5 times and once finished put it in my closet with shelves of others. Somehow, some parts dry and black spots were appearing everywhere. Has it happened to someone? What U do to remove it? Luv this bag, but it is really ugly. I do not think he had the J, because he is black or spotted.
