15-compartment mailroom sorter is made of durable, corrugated cardboard with a plastic-made coating that is tear-resistant for long-term storage. Additionally, the outside layer works with dry eraser markers (sold separately) as well as wipes down cleanly with a cloth. Label places per compartment permit you to personalize each room for effective business. Integrated guidelines along with assembly video clips allow you to thoroughly work up this station for short, use which is straightforward.
