Hi so I recently made a purchase in June of my beautiful DE speedy 30. I love her so much and she's still very new in my opinion but a couple days after starting to use her I noticed that the lock was already tarnished and nasty looking and not I've noticed that the lv buttons on the bag are what look like scuffed or marked !! I'm really careful with my bags...can anyone tell me why this has happened if it's normal and if there's anything I can do? I purchased her at the champs-élysées lv store in Paris.
