This is a Small Micro Machine Ferrari Testarossa Convertible in Silver (Color).  They are made of plastic and are highly detailed, note the interior.  It is about 1 1/4 inches long.  I bought this as part of a job lot and it is in 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.
