Found black roller suitcase with stickers at Starbucks on High Street.

I found a black roller suitcase at the Starbucks on High Street yesterday afternoon. It looks pretty new and has some stickers on it. It was left unattended for quite a while, and since no one came back to claim it, I decided to report it here. I'm hoping to return it to its rightful owner if they can describe the contents or any specific features.
