I cannot do
better than to quote the "Web Guru" of Micro Machines
Pure Micros
whose site contains far more information about Micro Machines
"Galoob
is well known for it's Micro Machine line of super small vehicles.
Most of the vehicles measured less than 1.5 inches!
They started selling them in the mid 80s and continued making them
for over 10 years.
Sales inside the US ceased in 1999 but continue in Europe
under the Hasbro name. Micro Machines are quickly becoming one of the hottest
collectable toys."
