I am selling this item because it didn't suit my needs, although I used it for a few days after purchase. It's in like-new condition, fully assembled. This is a convenient keyboard and mouse storage solution that attaches to a desk. It's highly stable and doesn't wobble even when typing. The box is not included. Although it's fully assembled, I will disassemble some parts for shipping.
