[Lost] Lost airpods in green silicon case

I've lost my AirPods on Tuesday Nov. 12th on the Science & Engineering Quad Courtyard near the Forbes family cafe, I think on this exact place https://www.google.com/maps/place/37°25'40.2%22N+122°10'24.8%22W/@37.427831,-122.1741082,192m/data=!3m2!1e3!4b1!4m6!3m5!1s0x0:0x0!7e2!8m2!3d37.4278314!4d-122.1735614

But when I came back it wasn't here anymore.

They are in a green silicon case with a black string.

It is the case on the picture but without the snap link.
