This is a completed and painted, fixed-pose figure.
From the Good Smile Company website:
The jacket cover of sound producer Mitchie M's album "Greatest Idol" featured an illustration of Hatsune Miku by the famous animator and manga artist Yoshiyuki Sadamoto. This illustration has now been transformed into a figure for fans to add to their collection!
The intricately sculpted details of her unique instrument as well as her dynamic pose filled with energy are sure to brighten up your day, and if that's not enough her adorable expression will finish the job!
