This is a Small Micro Machine USMC AV-8B Harrier Jump Jet Fighter Aircraft in Green Camouflage.  It is made of plastic and is highly detailed, note the markings, weapons and retractable landing gear.  It is about 2 3/8 inches long and has a wing span of about 1 1/2 inches.  I bought this as part of a job lot and it is in very good condition.  The coin in the picture is a Dime to show just how small this item is.

I will gladly combine these small items to save on the shipping.  Each additional Micro Machine item would be just $.25 for shipping.
