Price reduced from 18,000 yen to 17,000 yen!! Used only for open water diver course last year. My daughter, who is 160cm tall and weighs 51kg, with a slender upper body, used this. There are no pills on the shoulders, armpits, or back where the BCD is worn, and it is in quite beautiful condition. I purchased a full set of equipment for the open water diver course, but I am selling it because I am focusing on childbirth and childcare. Please note that returns and exchanges are not possible. Thank you for looking. Thickness: 5mm
