The World Of Micronauts

In 1976, an entire generation of kids were introduced to 3.75 inch, highly-poseable sci-fi action figures called Micronauts, that were far ahead of their time. The children that grew up playing with them have been waiting years for their return and thanks to Super7, that wait will soon be over!
