Black plastic glasses with blue pouch found near library

I found a pair of black plastic rectangular glasses this afternoon around 3:45pm outside the Kalispell Public Library on 2nd Ave East. They’re lightweight and look like standard mid-range frames, with a tiny scratch on the lower edge of the left lens and a nick on the top of the right temple. They came in a blue microfiber pouch with a white stitched logo that reads 'Mason'—not sure if that's the owner's name or the brand, but it's a nice identifying clue. If these belong to you, I’ll hang onto them here in Kalispell and can arrange a meetup or bring them to your preferred location.
