Purchased used a long time ago. I only read one part I wanted to, and then stored it on the bookshelf. I don't think there's much of a tendency for the book to open or have wrinkles, but since it's a book from over 10 years ago, there is some aging, including the cover, so please understand that it's a used book. A recipe collection that proposes a healthy diet. - Title: Japan's Number One Longevity Cuisine - Author: Mikako Yokoyama - Contents: Recipe collection related to healthy eating - Price: 1,300 yen (excluding tax) Thank you for looking.
