RavensburgerGraviTrax FlexTube Accessory - Elevate Your Marble Run Game | STEM Educational Toy for Kids Age 8 & Up | Compatible with All GraviTrax Sets | Boost Brain Power

My son loves these and he’s 12.

My 10 year old grandson loved this set so much we bought him all the accessories as well. It’s his favorite building set and he spends hours reconfiguring it. Good quality and educational for budding engineers!

Great quality pieces. Tubes worked great with marbles from kit. Suggested age 8+ is appropriate unless an adult helps assemble. Would buy again!

My kids enjoy building Gravitrax marble runs. This is a nice addition and makes for more exciting builds.

Muy bueno para fomentar la creatividad

This was a great expansion for the gravitrax base set. My son was very happy with it. I feel that you are paying mostly for packaging, and it is overpriced.

This is a good toy for anyone who love to build tracks

I love Gravitrax it this tunnel set's tab broke within 5 minutes out of the box while setting a track up. The price they are paid for these sets should account for something like that its sturdier and lasts alot longer than it did.

Flextubes lassen sich verstellen - heißt:Viele Möglichkeiten sie in der Bahn zu integrieren…

Jak każdy Gravitrax - doskonałe rozszerzenie posiadanych zestawów.

Het artikel is prima maar het werd verzonden zonder zonder doos waardoor ons Sinterklaas cadeautje niet meer gegeven kan worden omdat onze zoon het al gezien heeft. Beetje raar om speelgoed zo te verzenden…

Interessante aanvulling voor basispakket Gravitrax
