I don’t understand the idea or the attraction that some people have with ear plugs, but I’m not going to criticize it. There are a couple of Millennium Falcon related plugs are available on Etsy.
The first are these blueprint plugs by GameLinks in various sizes.
It’s an often used image but I think that they’re an unusual and relatively cheap addition to my collection. They have quite a lot nice genre designs for plugs and cufflinks in their shop.
The next pair of plugs are these “3d” ones by Man on Mars.
