While I'm getting the shop ready for the holidays, I couldn't help but open a Kumiai-Ki mystery box ( https://www.mountaintowntoys.com/product/kumiai-ki-the-mighty-labor-union-mech-3-75-jointed-action-figure-multi-color/ ) and compare it with one of the Super 7 Godzilla Mystery Box toys.
They look pretty good together, I think.
