Described herein are systems relating to packaging boxes. In some implementations, the packaging boxes include one or more trays used to support product cups, such as k-cups. The product cups, for example, can be used to hold tea, coffee, or flavoring. Some examples of flavoring include honey or other liquid flavoring a user can add to tea or coffee to adjust the flavor of the tea or coffee (e.g., honey comb and lemon grass, creamer, orange marmalade, mint peach, etc.). The packaging boxes can include a longitudinal axis parallel to the top and a long side of the box. The trays placed in the packaging boxes, for example, can have a similar longitudinal axis parallel to the longitudinal axes of the packaging box.
