The Bus model is 5 inch long by 1.5 inch wide by 1.5 inch tall. The manufacturer does not specify the scale.
Interesting features for this model include a main entrance/door that can open and close; a rear left side there is a stop sign that can be extended. The wheels are free rolling and made of rubber. Moreover the back wheels have pull back action, which means that it will wind up when you pull it back and it will roll if you let it go. The rolling motion is very smooth so be mindful of where you display it (or chuck the wheels). The detail and accuracy of the model is very impressive.
These models don't sacrifice on detail or quality to size. These are very realistic models. These models come is a big display box. They do not have individual boxes. They will be expertly packed and shipped.
