This item was purchased used several decades ago and has been stored for a long time. The specific details, such as the type, are unknown. ★It was washed and stored for a long time, so there is some light white staining, possibly salt, as seen in images 6 and 8★ This is a Maxim wetsuit for surfing. It was used by a male (smoker) who is 163cm tall and wears a size S. As anyone who has worn a wetsuit knows, even if you wear the correct size, it feels very small due to the tight fit. Therefore, it may also fit someone with a smaller build, such as a child. The sleeves have fraying as shown in images 13 and 14. In images 5 and 6, the white paint on the Maxim logo is faded.
