The name of this build piece is called “The Beckoning”
The prizes are actually just an acrylic transparent case with the black base, a heavy glass trophy, and a assembled Silver color coated (plated?) Mega Size RX-78.
In case if anyone thinks that I’m lying about my status , you may check it here at this official website: https://g40bc.bandainamcoasia.com/my/winner/
Will post images and videos of this build soon, thank you for tuning in.
