Which Sentai toy has the biggest box?
 

I'm just wondering as I want to collect almost every post Zyu mecha which box takes up the most space? I think it might be Ushi origmai's.

Anything in that "giant final/carrier" category.

SaiDaiOh's huge.

I was surprised by how big the boxes for Tei-Oh and Machalcon were when they showed up.

My friend told me that Black Gorai Sepuujin's box is the largest in terms of width while Ushi Orgami's is in terms of depth.

On occasion, they'll release a box set of 2 mecha, like the LiveRobo and LiveBoxer 2 pack.
I assume those boxes will be bloody huge.
