This is "Shin Kankokugo e no Tobira" (New Door to Korean). It costs 2700 yen + tax. It has only been used once or twice. As you can see in the photo, there is a fold on the cover. I don't think there is any writing inside. There are scratches, folds, stains, and age-related deterioration from use, but please understand this before purchasing. Please refrain from purchasing if you are very concerned about the condition, as it has been stored at home.
