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 for one year. Also includes: Summer Vacation Every Study Science and Social Studies Pre-Study Workbooks Calendars and Every Information Bureau (similar to a newspaper) may be missing in some cases. 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; all materials with categories are "High Level." Some items 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. I am also selling these elsewhere, so please comment before purchasing. Thank you.
