Lost black laptop bag containing an external hard drive and noise-cancelling headphones at Appleton Plaza.

I misplaced my black laptop bag while shopping at the Appleton Plaza last Saturday. Inside were my external hard drive and a set of noise-cancelling headphones. I realized it was missing when I got home, and I retraced my steps in the area but couldn’t find it anywhere. If you have seen it or found it, please let me know!
