The doors can open revealing nice details. The wheels are made of rubber and they roll very smoothly, so be mindful of where and how you display it (don't have it roll off a table).
Particular to the dump truck model, the bucket can be tilted and you can see a very nice arm that can extend. Moreover, the tailgate does pivot at its hinges.
The second dump bucket attaches to the truck and it too has the same arm and tail gate articulation as the main bucket.
Together the truck and both buckets measure about 22 inches long.
These models come in individual window boxes.
Note that these are not really toys. They would not survive being played with regularly.
