Box Packing Puzzle

Three boxes are all labeled incorrectly, and you must get the labels right. The labels on the boxes read as given below.

To gain the information you need to move the labels to the correct boxes, you may remove a single item from one of the boxes. You may not look into the boxes, nor pick them up and shake them, etc.

Can this be done? If so, how? If not, why not?
