Muuto’s Arrange Desk Tray can be used either as a standalone organizer for papers and office supplies or as part of the Arrange Desktop Series storage system. The Arrange Desktop Series, designed by BIG-GAME, is a practical, convertible desk organizer whose parts you can use either stacked on top of each other in various ways or as separate trays and boxes. Made from 100% recycled plastic, the Arrange Desktop Series is also an eco-friendly alternative for storing office supplies – and why not other small items around the home, as well.
