The Prostand book cover set is designed specifically for 5th grade students studying in the Romanian language track to keep their school materials tidy. This package includes 9 transparent polyethylene covers that protect books from dirt, moisture, and general wear throughout the school year. To accommodate different book sizes, the set provides four larger covers measuring 362x422 mm and five smaller ones at 245x317 mm. These lightweight, clear sleeves allow you to see the book covers while ensuring the pages stay clean and intact during daily transport in a backpack.
