The Prostand book cover set is designed to keep fourth-grade Romanian language textbooks clean and intact throughout the school year. This collection includes seven transparent polyethylene covers that shield pages from moisture, dirt, and general wear, ensuring that books remain in good condition for longer. You will find four larger covers measuring 362x452 mm and three smaller ones at 245x337 mm, providing a versatile fit for various textbook sizes. These lightweight plastic sleeves are an easy way for students to protect their learning materials from the daily rigors of carrying them in a backpack.
