Shades of the "Love Squall" ending from Red Jacket series.

Within the past couple years Bandai has started releasing exclusive kits at various toy & model expos in Japan. They're typically slightly modifications of existing kits using special coatings or clear parts. Generally their boxes are just the standard box art with a bit modification or a logo for differentiation. This year's Art of Gundam expo releases featured several kits never released in a clear format with, what I believe to be, a stunning box design.
