This is a Happy Smile Licca-chan doll made by Licca-chan Castle. It's a version of Licca-chan with a different expression that is no longer sold. This Licca-chan, with her smiling face, was the most popular model. An adult would dress her up and display her in a collection case to prevent dust from accumulating. Because the collection case wasn't very large, she was stored in a closet after being displayed for a short time. Since the doll was released a long time ago, there may be some age-related deterioration. If you understand that this is a used item and are interested, please consider purchasing it.
