This new clear paper tray organizer, made of high-quality PET material resembling acrylic, is both sturdy and stylish. With an inner size of 9.76x12.8 inches and outer dimensions of 10.04x12.99 inches, it's spacious enough to store A4 documents, notebooks, and books. Thoughtfully designed, it features a center groove for securely holding small items like pens, and a convex outer groove to prevent objects from rolling out. Anti-skid pads placed in four bottom circles ensure the 3-tier stackable trays stay in place. Steel pipe supports between layers enhance load-bearing capacity and accessibility, allowing items to be retrieved from any side. Its upgraded portrait orientation, thickened construction, and reinforced hardness provide superior durability and resistance to deformation, making it a practical and long-lasting addition to any desk.
