Black Anker Bluetooth speaker with dented rim

I lost my black Anker Soundcore portable Bluetooth speaker yesterday around 3pm near the Starbucks at Watertown Square on Main Street. It's about 6 inches long, with a matte black finish and a small dent on the top rim. I noticed a blue fabric strap that is part of the charging cable loop, and there’s a tiny sticker with my initials 'PP' on the bottom. It’s important to me because I use it daily for audiobooks during workouts, and I really need it back. If you found it, you can drop it off at the Watertown Public Library or reply to this listing and we can arrange a pickup.
