NIB Clear 300 Series

[Super]

My guess (not based on any fact) is that pretty boxes with catchy graphics are made to attract the eye of buyers on a stores shelf or, in this day and age, online listings. Where in the cases of Limited, non-retail or giveaway trains there is no need to visually attract the consumers eye. Because of this it can also save the manufacturer some cash as they would not have to design and print out fancy cardboard graphics which would cost more to produce than a plain box. At least with the above example they have windows in the box showing off whats inside where many others do not. IMO...I also see these minimally made boxes as collectors items too as some just have a printed name or windows and might be just as desirable to complete a collection as the eye catching ones.
