ColorStak letter trays don’t just look great, the products are incredibly sturdy and of high quality with a gloss finish. These bright green, angular paper trays stack neatly on top of each other, so you can save space on your desk. Without buying separate risers, you can build up as many trays as you need. Designed to hold A4 and foolscap documents, folders and brochures, these strong ColorStak Letter Trays come as a set of 2. You can stack them traditionally - one on top of the other, but they will also stack at 90 degrees and front to back. Choose the arrangement and colour combination that best suits your needs.
