Ineed help finding a very specific gift

Long story short, tomorrow is one of my only days to roam around by myself, and I was hoping to find a specific gift for a coworker before I go home. He collects shot glasses with country or city names on them. I got him one from Thailand that said Bangkok on it. Now I'm trying to find one that either says "Davao" or "Philippines" on it. Does anyone have any idea where I can find one?

Thank you in advance!
