Listing on behalf of my father. This is a custom-made item in the Umizaru (Sea Monkey) specification. It cost over 1 million yen at the time. Made for a person with a height of 168cm and a weight of approximately 75kg. Used about 3-5 times. A professional diver recently used it, so I believe there are no issues with its use, but there is no warranty. This is a used item, so there are scratches and stains. Please check the photos. Please ask any questions in the comments.
