Here is a set of 3 Kumon textbook binders. ★ You can mix and match French and German if you purchase 3 binders. ★ The string may be black. (Cannot be combined with English, Math, or Japanese materials due to different prices) ★ If you purchase without a comment, we will send you 3 French binders. You can close and store Kumon prints. The thickness can be adjusted for 200 sheets or 400 sheets. It's difficult to keep the vast amount of prints when you start learning, 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, etc., when you don't understand something. They fit exactly 200 or 400 sheets and don't create wasted space. Easy to put in a bookshelf. 《Material》Paper Please also see ↓ #Kumon related, children's enjoyable collection If you have any questions, please feel free to comment.
