Black Anker charging case for wireless earbuds

I lost my black Anker charging case for wireless earbuds yesterday around 3pm near the Winspear Opera House on Flora Street in the Dallas Arts District. It's matte black plastic, about the size of a credit card, with a small scratch on the top-right corner and the Anker logo still visible on the lid. Inside the lid there's a tiny sticker with my initials 'PK', in black sharpie, and the earbuds themselves weren't in the case when I realized it was missing. It was a gift from my sister, so it's really sentimental to me, and I really need it back. If someone found it, I'd truly appreciate it getting back to me.
