As a niece, I could once again show off with this gift! The two boys, aged 8 and 6, were happy and got to work in their special LEGO room!

Putting together the boat and the airplane was quite easy. However, it's a shame that you also need the submarine to assemble the airplane.
It's great that you can make more things with it.
really fun to build and play with
The item was very well received by the birthday recipient.... absolutely fantastic... It's great that it was also delivered so quickly... I didn't even have to leave the house... fantastic...
