We have given the 1m large marble run the kindergarten class and the children now test extensively what roll down / drive may be faster, which is entangled with the intention of passing them, etc.
The locomotive can even drive upside down, find the children particularly funny.
The bullet train and the accessories from Trihorse are very well made.
The customer contact with Trihorse is very fast and friendly.
Shipping is also fast and neat!
***** Absolutely recommendable!
