I don't see how Hasbro's packaging is less customised than TakaraTOMY's. TakaraTOMY also have price points and standard packaging sizes, for example, all Deluxe Henkei figures come in the same size card and blister package. Also, aren't they all customised to a degree because they have individual toy name, package art, tech specs, photos etc.? The inside plastic tray would also have to be custom moulded to fit snugly over the toy too.

I personally don't like the feeling of paying big bucks for a toy where half the box is full of air. :/
