Bigso’s Walter Letter Tray helps avoid untidy piles of paper in your work area or can be used as stackable paper trays for classroom. The 13.1in x 10in x 5.2in size lets it store A4 or letter size documents such as papers, correspondence, clippings, important accessories, and more! This paper tray for desk offers dual functionality as a letter tray and a full-width drawer, and the rubber feet work hard to assure stability and protect the desks and shelves from scratches.
