You're buying a garage-kit resin model/miniature, from ZandrisIV. It bears an uncanny resemblance to a very popular character from a very popular CGI movie series, but this is not she, this is a "Female Titan," and any resemblance to any famous character named Elsa from any famous movie titled "Frozen" is purely coincidental.
This model is provided new, and unpainted. The first photo is from the creator, not my own work, and purely to demonstrate what can be accomplished with proper assembly and painting. No base is included. It stands around 150 mm (6 inches) tall.
