This is English教材 for ECC Junior students (2-3 years old). I am also selling another item of the same level. (At ECC, the level goes up every two years. In the first and second years, students study with教材 of the same level but different content.) There are no writings in the教材, but since two children used them for one year each, there is a feeling of use. If you are okay with picture books borrowed from the library, I think it's okay. The names on the back covers of the three books have been erased. A separate booklet with Japanese translations is included. ECC教材 are very good, so I hope someone will use them☺︎ The content is perfect for English study at home. The教材 cost about 20,000 yen when purchased. - Set Contents: Rainbow Factory PT 3 books (2 storybooks, 1 English educational book, 1 DVD, 1 CD) - Language: English - Target age: For infants - Theme: English educational activities, stories and songs - Publisher: ECC
