This is the same head mold as the standard release SD girl Nono. The default eye size is 22mm. The standard release of Nono was discontinued by Volks in September, 2010, so she then became FCS-only head mold available to all locations. She was then discontinued at Sumika locations on September 30th, 2020. Following the usual pattern, she was then discontinued from Tenshi no Sato and Tenshi no Mado on January 31st, 2022.
