This is the same head mold as the standard release SD13 girls Sara, Nana, Kira and Megu and the old FCS heads F-22 to F-25; it is often referred to as the '13 four sisters' head. The default eye size is 18mm but 20mm is also fine. This head mold was discontinued from Sumika locations on September 30, 2014, and was completely discontinued a year later in September 2015. It can no longer be ordered in any location.
