I bought these to study for a certification, but I haven't had time to use them and have put it on hold. How about it for someone who will use them diligently for exam study? If purchased from a major online retailer, the total would be over 4000 yen. 【Condition】 Opened. The white marker and red and blue markers (1 each) were used once for a test write. The others are unused. There is some color transfer on the opened white marker (photo 7). This is a general used item, so please refrain from purchasing if you are sensitive to such things. No returns or refunds. #ExamStudy #StudyBoost #RedBook #Certification #ZEBRA #CheckPen #CheckSheet #Memorization #Zkai #MidtermExam #EntranceExam
