The GraviTrax Junior Trap add-on introduces an element of surprise to children’s marble runs. The marble disappears inside the add-on and reappears on a lower level, encouraging experimentation, planning, and the joy of discovery. Compatible with all elements of the GRAVITRAX JUNIOR system.
Made from high-quality wood-based bioplastic that feels pleasant to the touch and is eco-friendly. Ideal for young builders aged 3+, who create their own themed worlds while developing fine motor skills, logic, and imagination.
