This is a Small Micro Machine Zephyr T-30 Futuristic Tank in Green & Tan Camouflage.   It is made of plastic and are highly detailed, note the weapons.  It is about 1 1/2 inches long and 1 inch wide.  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.
