Large poster for the shop?
Work in progress on April 24th.
Runner H is "XXXG Frame 2", while Runner c shown more than a week ago is "XXXG Frame 1".
Maybe Runner X is the runner that contains identical inner frame parts for all Wing Gundam series MGs, while Runner H is the runner that has parts unique to a particular Gundam.
MG Wing Gundam will be released tomotrrow (April 28th) at 4,200 Yen (inclusive of tax).
