This is one of the few props released by production to the public from Aeon Flux!
As I recall the scene where Aeon and Freya were trying to enter the city of Bregna the barb quills came up from the grass turf when they were detected, protecting the city from intruders.
This is a protype for the quills and it is about 3 inches long.
This prop comes with a Certified Copy Certificate Of Authenticity as it is one of 5! :-)
