Z-Kai Elementary 2nd Grade, one year's worth from April to March. All materials are completely blank. Includes: Every Study Every Study Support Future Thinking Skills Experience Drill Z (All for one year) Also includes: Summer Vacation Every Study Science and Social Studies Pre-Study Workbooks Calendars and "Every Information Bureau" (newspaper-like materials) may be missing. Some materials have been cut. (I believe it was one month's worth. There is no problem with usage. I apologize if there are any others.) The academic years vary. It seems that the "High Level" category is no longer available for the newer academic years; materials with categories are all "High Level." Some materials are unused, but I have handled them all. Please consider this if you are not concerned about minor details. Please comment if you have any questions. Thank you.
