This is a Small Micro Machine Galaxy Voyagers Dystressian Pursuit Vehicle.  It is made of plastic and is a highly detailed, note the teeth.  It is about 2 inches long and 1 1/4 inches 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.
