Gucci Tourtise colored sunglasses, authentic

Gucci Tourtise colored sunglasses, authentic. There is wear with use. See photos. No scratches on either lens that is visible through the glasses or I can see. That being said, they are used. The most wear is on the gold Gucci logo. You might be able to fix. No case:( The are a little big- loose feeling. I have worn and loved them as a closet staple. But new glasses have realistically replaced. Also I think one screw could be tightened more.
