Query: Unused...

Well, it seemed a no brainer to have a base for the Lego bricks my son got along with this item for Christmas. Unfortunately, this piece of plastic has been overlooked and unused since it was opened and has proved unessential for my children's enjoyment of Legos. To it's credit, it has held up after being stepped on, flung, and tossed aside in room cleaning. But I do regret spending the $15+ shipping to get it. Unless you are a die-hard lego sculptor and/or need it, skip this item. Just another thing to clean up along with the hundreds of bricks they actually play with.
