This was purchased at Hama Gakuen in the fall of the 6th grade for a current 1st year junior high school student. Originally sold as paper, it has been cut along the dotted lines to create flashcards for memorization. It's easy to carry around, making it perfect for reviewing on the train, in the car, or just before a test. When shipping, the ring will add to the thickness, so I will secure it with a rubber band and remove the ring for packaging. Also included is a handout from a mini-lecture on the day of the entrance exam. Please make good use of it. While it is in good condition, please understand that it is a used item before purchasing. Thank you for looking.
