I purchased this textbook about 8 years ago as a school requirement, but I never used it in class and have kept it in storage. It is unused, but there are stains on the front and back covers. Please purchase only if you understand that it has been stored at home. - Title: Concrete Structure - Author: Shinobu Tsunoda, Kazuo Takemura - Publisher: Corona Publishing Co., Ltd. - Year of Publication: 2001 - Language: Japanese - Price: 2200 yen Thank you for looking.
