Ravensburger GraviTrax FlexTube Accessory - Marble Run & STEM Toy for Boys & Girls Age 8 & Up - Accessory for 2019 Toy of The Year Finalist Gravitrax

Granddaughters enjoy this addition to their GraviTrax set that I gave them for Christmas. They play with it for hours

Big fans here! ( 4 years old and my significant other 48 ) They received a family gift of a GraviTrax set for Christmas last year and each holiday they have received more to add to their growing set. They now have a set up in our living room and play with it for hours building and rebuilding their track. This is a really great piece to add some fun to your setup.

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

This marble maze set is awesome, my whole family enjoys playing with it.

I love Gravitrax it this tunnel sets 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.

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.

My teenage grandson loves gravitrax!
