This is a posable action figure from the Nendoroid series.
From the Good Smile website:
From the anime series "Miss Monochrome -The Animation-" comes a Nendoroid of the android aspiring to be a popular idol, Miss Monochrome! Monochrome's close family member "Ru-chan" as well as alkaline batteries and a battery box to keep her powered are all included as optional parts.
A winking expression is also included to recreate the popular dance scene from the ending theme. The Nendoroid box seen in the anime is also included, allowing Miss Monochrome to take pride in her accomplishment of becoming a Nendoroid!
