This is an injection-plastic figure kit.
From the Good Smile Company website:
The popular characters from "Strike Witches" are joining the minimum factory series! The first to join the collection of 1/20th scale plastic model kits is the main character with exceptional potential - Yoshika Miyafuji!
The model kit has parts separated into different colors, meaning that just putting the model together looks great even without the need for paint. Decals for her eyes as well as various markings and lines are also included. Her Strike Unit is the popular "Shinden" unit, and she is equipped with a modified Type 99-2 Model Two 13mm machine gun in her right hand. A special stand to display her flying is also included. Be sure to add the cute and energetic Strike Witch to your collection!
