GraviTrax Junior gives children from the age of 3 a child-friendly introduction to themed marble track worlds.

GraviTrax Junior is an interactive marble run system for children aged 3 and up. Boys and girls create their own marble run worlds, which can be flexibly decorated to create individual themed worlds. Building and playing fun are combined.
GraviTrax Junior can be expanded as desired by adding components or special elements. Sets with theme-specific decorations allow children to create their own worlds - for lasting play fun.
