Toy purchased in Oahu, Hawaii approximately 40 years ago (around 1987). It swims using a screw mechanism. I haven't opened it, so I haven't tested it, but I bought two at the time and they did swim. The packaging is slightly warped, but there are no special stains or damage. It's a retro item, so returns are not accepted. Package size: 21cm wide x 19cm, Doll length: approximately 18cm.
