I accidentally purchased this, so I am selling it. 1. You can write on it while it's filed! 2. It doesn't reflect stage lighting! 3. It's a binder type, making it easy to replace and add pages! 4. It also comes with pockets similar to regular clear files. Model: MR-20 Number of sheets: 30 holes, 20 sheets Compatible size: A4 Thank you for looking! Thank you.
