SmartMax Build XXL
This is the biggest SMARTMAX balls and rods set. It has standard pieces and you can use it together with any other SMARTMAX set. However, the really interesting and unusual thing about this set is its box. Both the lid and the bottom of the box have special depressions to hold pieces of the set in a fixed place. This way, you can use the box as a sturdy and reliable base for your crafts, and build higher and bigger.
