Black leather Tumi briefcase with shell charm

I lost my black leather Tumi briefcase yesterday around 3pm outside the International Market Place on Kalakaua Avenue in Waikiki. It's a bit scuffed on the corners, with a red seashell charm attached to the handle, and there's a small sticker inside that says "Property of K. Nakamura". Inside, you'll find a USB-C charger, a copy of my passport, a signed contract for a project, and a faded photo of my grandmother tucked in the inner pocket. It has sentimental value and I really need it back for a big meeting next week.
