VGUC Swiss Gear mini bag

VGUC Swiss Gear mini bag that you can sling across your back or your chest when traveling. A great little bag. Only selling it because my mom gave me hers (that has sentimental value). There is one little spot along the zipper and I don’t know what it is. I haven’t tried to remove. Approximate measurements 11 x 13 x 4.5”. Clean interior. From a smoke free and dog friendly home.
