This is a Small Micro Machine ZX-300 Sky Hawk Jet Aircraft in Green Camouflage.  It is made of plastic and is highly detailed, note the weapons and retractable landing gear.  It is about 2 1/8 inches long and has a wing span of about 1 1/4 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.
