This is a set of 5 Kumon educational material binders. ★If you purchase a set of 5, you can combine them with German and French. ★The string may be black. (We cannot accommodate combinations with English, Math, or Japanese, as the price range differs.) ★If you purchase without a comment, we will send you 5 French binders. You can close and store Kumon printouts. The thickness can be adjusted for 200 sheets or 400 sheets. When you start learning, it's difficult to keep a huge amount of printouts, but it's hard to throw them away... so you can file them by subject. Also, for those who have advanced to higher-level materials, their own solved materials become the best reference books, so filing them by subject is a great way to remember old grammar when you get stuck. They fit exactly 200 or 400 sheets, without creating wasted space. Easy to put in a bookshelf. 《Material》Paper Please also take a look at ↓ #Kumon related, children's enjoyable collection If you have any questions, please feel free to comment.
