erm...those are plastic models....scale 1/24. they come with pre-painted body. you can choose to paint or not to paint it but, normally i paint it (spray it using tamiya spray for the body and paint smaller parts using tamiya acrylic paint). due to limited budget, i use only tamiya can spray. can't afford to buy a paint brush...the effect will be better if there is a paintbrush around.

too bad that my skills are not up to the level...just like what we can see in tamiya's masterwork collection.
