Thank you for viewing. New Elementary School Problem Collection: Arithmetic - Entrance Exam Edition - Stage 1 (Grade 4) Price: ¥2,420 This problem collection is not available in general bookstores. I purchased it at a cram school in March of this year, but I am selling it because I will not be using it. It is new and unused, but it has been stored at home and the corners are slightly bent. Please refrain from purchasing if you are concerned about this. Thank you. #EntranceExam #NewElementarySchoolProblemCollection #Arithmetic #ProblemCollection
