Keep them happy for hours
A really great way of encouraging your young ones to work our patterns and design and my grandson loves it and it keeps him off the Nintendo for a while!

Good bargain, all in German for some reasons but cheap
For £6.71 it's a decent set, gravitrax is normally much more pricey. It is all in German, for reasons (unknown)

Great addition
My son loves this addition to his Gravitrax set. Works well with the other add ons, too.

Nice fun
Great fun for the kids, however, make sure you’re gonna buy starter Box 1st, and then you can buy this box as a extension

Gran nivel de acabado, piezas muy resistentes y que encajan perfectamente entre ellas. Ideal para aportar más variedad al juego báse y añadir más piezas a las construcciones.

Die Tunnel erlauben es den Kugeln, unterirdisch zu rollen und neue Herausforderungen zu meistern. Die vielfältigen Möglichkeiten der Gestaltung fördern die Kreativität und das räumliche Denken der jungen Baumeister. Die Erweiterung ist leicht zu integrieren und sorgt für abwechslungsreichen Spielspaß. Ravensburgers hohe Qualitätsstandards garantieren eine langlebige und ansprechende Spielerfahrung. Insgesamt ist die GraviTrax Erweiterung Tunnel eine empfehlenswerte Bereicherung für alle Fans der Kugelbahn.
