This is a completed and painted, fixed-pose figure.
From the Good Smile Company website:
From the popular "Fate/stay night" spin-off series "Fate/kaleid liner Prisma Illya 2wei Herz!" comes a figure of the main character Illyasviel von Einzbern in her 'beast' mode! Her long silky hair that drapes over her shoulders, the soft looking gaps of bare skin that is contrasted by the fluffy outfit she wears creates a figure that any fans of Illya will enjoy in their collection!
