3DWorldFigures has not one, but two Krystal figures available for purchase on the Etsy store. These 3D printed figures are 12-inches tall, fully painted, and come with a little scene/stand to hold each in place. They are each around $140 to $145 dollars, with unpainted versions available for $120. There is an Adventures version and a new Assault version.
Several members of the Krystal Archive Discord have purchased each one of these, and I can report that as of a few days ago, even the newer Assault version had arrived for someone who purchased it. So these are real and available now!
