Black North Face backpack with blue zippers

I lost my black North Face Borealis backpack yesterday around 3pm after I left the ISU bookstore on 7th Street. It's a medium-sized bag, a bit worn at the corners, with blue zipper pulls and a small red carabiner clipped to the top handle. Inside are my math notes, a pink notebook, and a tangled USB-C cable sticking out of the front pocket; there’s also a band sticker on the front panel. It has sentimental value because it was my everyday bag for classes this semester, and I really need it back!
