The English idioms are new. These were purchased from Z-Kai and stored without use. The CDs are unopened. The Gakken strategy book was purchased on Mercari and has not been used. I couldn't find any writing inside. Would these be suitable for junior high school students or exam candidates who are looking to start listening and idiom practice? I hope these items will be appreciated by those who understand that they are home-stored and used items. Thank you.
