By using the following example, I'd like to make sure a natural English expression. Example: (Correct combination) Box A + Teddy Bear Box B + Vase (Incorrect combination) Box A + Vase Box B + Teddy Bear So as not to deliver by the incorrect combinations, I'd like to indicate about the situation to my colleagues. How do native English speakers say the above incorrect combination in English? My idea is "The products are wrongly placed in the boxes each other." Is that OK?
