Are you a Hubelino fan? Could your constructions use a little more challenge? Or do you simply have too many building blocks and track components to fit? Then this green base plate is perfect for you! This extra-large plate with 560 studs gives you extra space to build your marble run. This makes your marble run even bigger, cooler, and more fun! An extra plate like this is very useful; without the base plate, your marble run won't stand securely! Also available in blue. Smaller versions are also available (140 and 280 studs).
