PRODUCT DESCRIPTION
This set contains both more balls for even greater marble run fun as well as cool storage boxes for existing GraviTrax balls. The accessory ball box is a must for all GraviTraxers. The four boxes are designed in the cool design of the GraviTrax height stones and in the colours green, grey and white. Two of the boxes are already filled with a total of 12 silver and colourful GraviTrax balls that get the train action rolling. The other two boxes serve as an ideal storage option for existing balls. GraviTrax is a flexibly expandable, interactive marble run system for children aged 8 and up: With GraviTrax, children, teenagers and adults not only build simple marble runs. They create unique marble run worlds. By freely designing the marble runs and exploring the rolling behaviour of the balls, the understanding of science is sharpened and gravity can be experienced up close. The GraviTrax universe includes three exciting lines CORE, PRO and POWER. All GraviTrax lines and products can be freely combined. Thanks to countless extensions with classic components or stones that allow special action and tricks, the GraviTrax universe can be infinitely enlarged. So everyone can tinker, try out and expand beyond themselves.
