This is the same head mold as the standard release SD girl Rio. The default eye size is 22mm. Rio is no longer sold as a standard model, and in fact Volks never released her in pureskin. As such, she became a FCS-only head mold. On September 30, 2014 the head mold was discontinued from Sumika locations, and completely discontinued a year later in September 2015. It can no longer be ordered in any location.
