The Silent Service (2023 Film) Keychain This is a keychain from the movie "The Silent Service." It features the logo of the Seabat, the high-performance nuclear submarine that appears in the film. It's made of brown faux leather and has an embossed logo with silver edging. It was sold as a theater merchandise item for the 2023 film. I opened it, but it has been stored at home unused. There are some minor scratches that appear to have occurred during storage. Please refrain from purchasing if you are concerned. Thank you for your understanding.
