Scratches or marks on the glass surface
The glass go through several stages of production before they are ready for installation. The tempering of the panel may generate different abstract patterns on the surface. In some cases, and seen from some angles, you can see like scratches on the glass. It's a perfectly normal when it is tempered glass. (You can also see this on your car windows).
The packaging marks and fingerprints are removed with normal cleaning products.
