Original retail box includedCondition: Box shows noticeable age and storage wear including edge wear, creasing, scuffs and tearing around the mouse display opening. Please look closely at the photos for the exact cosmetic condition. I have not removed from the box to test, the item has remained in the original box/packaging and is being sold As Is. Great piece of older Microsoft hardware for someone looking for this particular keyboard layout, a replacement setup, or a period-correct accessory for an older PC.
