Blue contact lens case with initials P.J.

I lost my blue contact lens case yesterday around 3pm near the Rushmore Mall entrance on Mount Rushmore Road in Rapid City. It's a small translucent blue plastic case with a white lid, and I wrote my initials 'P.J.' on the lid with a black Sharpie. Inside are two lenses in saline, and there's a tiny red heart sticker on the bottom that makes it easy to spot. This case is my spare pair for eye safety and it has sentimental value—I'd really appreciate getting it back.
