"The First Book to Read When Asked "Do You Exercise?" at Your Health Checkup: A 20-Day Program Starting with 3 Seconds a Day, Without Giving Up" by Seiichiro Kuchiki Price: ¥1650 (tax included) I've only read it once, so the condition is good. However, it is a used item, so I would like to sell it to someone who understands this. #SeiichiroKuchiki #Seiichiro_Kuchiki #Book #Society/General
