This Prostand set provides a practical way to keep second-grade Russian school textbooks in good condition throughout the academic year. Made from transparent polyethylene, these covers allow you to see the book titles clearly while shielding the pages and bindings from dirt, moisture, and general wear. The pack includes six covers in total, divided into two sizes to fit different textbook dimensions. You will find three pieces measuring 242x425 mm and another three measuring 245x357 mm, ensuring that the most common books for this grade level are properly protected from the daily rigors of a school bag.
