This Monkey King building box set is brand new I opened the box to show everything that is included a lot of people think it's a pre-done model because the box is so huge this Wukong model lights up and is very easy to put together these do take about an hour but when you're finished they're well worth it these are great activities to do with your children it will definitely teach them progress, the box is huge I placed a dollar bill next to everything for scale.
