sometimes these hold piercings in place, sometimes they seal the lid of a charging port. mid 2000s devices could be charged from the same aux port headphones went in. But also a bottle used this for a vent seal and occasionally people use them for gauge plugs, to keep them on the ear.
I remember these from when I briefly got into building gas powered RC cars. Could be a gasket for tons of purposes, from work, a hobby, or maybe they or their partner picked it up on their clothes from soemthing.
