Standard Ron Kokugo (Japanese Language Textbook) - Publisher: Daiichi Gakushusha I've only opened it a few times. There are some crease marks from opening, but it hasn't been used much. I think it's in good condition, but please understand that it is a used item before purchasing. Please be sure to check the condition in the photos. * I checked for any writing and didn't find any, but please purchase only if you are willing to accept the possibility of any oversight.
