Authentic Chanel - Foundation Brush bag

Hi everybody! I’m doing some spring cleaning and thought I’d put this out there in case anybody could use it. I purchased a foundation brush from the Chanel counter at Nordstrom in 2011 and the brush came with this bag. I don’t need the bag and it’s been sitting in my drawer since 2011. It’s too well-made (and of course it’s Chanel) I couldn’t bring myself to just give it away. It might be good for sunglasses and/or any other Chanel accessories you might have. I took a picture of the Chanel foundation brush for reference that I bought it with, but the brush is NOT for sale. Also, there is a white mark (not sure what from) that’s on the back of the bag.
