Recently purchased, these are the two volumes of Atsuko Hatanaka's "Tenka Muteki no Suuteki Shori" (Unrivaled Numerical Reasoning), famous as a crocodile book for high school graduates. They are new and unused. They have been stored with covers. I have never read them. Retail price: 1650 yen I am selling them because I have no plans to use them. Please refrain from asking for a price reduction. Many people don't buy even if I lower the price. Please comment if you are interested.
