The office desk storage box breaks through the traditional black or white monochrome design, choosing bright wood colors to showcase our youth and fashion. The bookshelf is also an excellent decoration for the desktop, winning the admiration of neighbors. Multiple colors suitable for any countertop. Corner bookshelves are also the best gift choice for boys, girls, students, children, friends' birthdays, weddings, Christmas, Thanksgiving, and New Year. The expandable bookshelf length can be stretched from 13.4 inches to 24.4 inches, meeting our different storage requirements to the greatest extent possible. 5.9-inch depth saves space and can be placed in any corner of a desktop, window, or countertop. The five tiered office desk shelves effectively organize our daily items in an orderly manner, greatly improving our space utilization. Reasonable size, designed specifically for A5 paper and books, very suitable for students to use.
