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 all the vast 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 take a look here ↓ #Kumon related, children's collection If you have any questions, please feel free to comment. Paper Size: A5 Set Quantity: 5 sets
