I took a risk knowing this piece was MDF. I am pleasantly surprised and say the risk paid off! It is flat pack, but these guys know how to pack a piece for relentless shipping. I request from Porch delivery, but it was left outside the garage and it rained. Oh no!!! The rain penetrated The cardboard in places, but there intentional packaging saved the day! The ultimate Lego set, all the pieces arrived, the directions were clear, and it all fit together with ease, no muscling to get just so. Two thumbs up!
