“Yep. It's a baseplate alright. It's gray. It's square (15" by 15"). And it is LEGO brand.Concerning the quality, it is somewhat flimsy. I have a couple of other baseplates that seem thicker, although for the size of this one it makes sense that it would have a bit of give. I would have preferred a thicker plate with holes on the bottom, as well, but for the price this one served its purpose.This is a fairly large baseplate--many of the available plates are 10" x 10", so this one provides double the total area. My daughter loves it just because of all that she can fit on it, and it is certainly better than the smaller ones for her to set up a "park" for all her many, many LEGO people to play around.”
