Build something no one else can with the new QUBTRIX blocks!
The START STAIRS brick allows the initial section of the track to be built. Alternatively, it can be used to intercept a marble falling from a higher level-e.g. through a FUNNEL brick. It can also be combined with, for example, the vertically aligned LINE brick.
Number of elements: 1x START STAIRS block, 1x eco doypack
