see i thought it was something like as well but it mentions this
>また、ラボラトリーエリア内に実物の成形機を設置し、眼の前でプラスチック成形を実演、成形品がプレゼントされる。
You get something i guess. Maybe I read it wrong at first? the website says this
>Visitors can receive the original package they designed and the runner plate of their chosen model as souvenirs.

at least the blue model is pretty cute. I also emailed them about how to even get tickets since they use p-bandai as a ticket vendor and tickets close prior to one week which if you want to go on vacation is kind of shit.
