Z-Kai Year 1 (Ages 3-4) Pair Zetto, Thinking Skills Workbooks, etc. for the year from April 2020 to March 2021. Everything in the photos is included. (Contents) ① Pair Zetto: 12 books ② Pair Zetto i: 12 books ③ Thinking Skills Workbook: 12 books I mainly used a Frixion pen to write, and I erased the parts written with the Frixion pen. I used colored pencils for problems that involved drawing, so those marks remain. The stickers have been applied, but they can be peeled off and reapplied. There are no major scratches or tears, and I think they can still be used. I apologize if I missed anything.
