With the black, I wouldn't worry about it much, but certainly treating it wouldn't hurt. I treated my ocean colored woven Olivia as per Lexie's advice with the Wilsons spray because the color is just so gorgeous, and I was concerned about any little flaw marring her perfection. My daughter has the black Skye, which she has carried daily for a year, and the leather has gotten more and more beautiful with time. She is not one to be overly cautious with her bags, the bag has not been treated, it looks better today than it did brand new! Best wishes for a long and beautiful realtionship with your new Gryson Olivia!!
