This is a Stella McCartney bag.
I've had it for about three years. I used it for work, so I used it almost every weekday, and used it quite frequently.
There are many stains on the inside from spills, but no stains on the outside.
There is also damage to the back of the handle, but that is only on the visible side. It is generally dirty, but the damage is worse on the contents, bottom, and back, so the logo side is still relatively clean, so the dirt is not noticeable to others when you carry it around.
Discount on multiple purchases.
