Ninodoll has listed a new BJD head pre-order for May 10th on the website. The heads are cast in normal skin resin and are sold blank.
From the company:
Ninodoll preorder schedule has been delayed because of currency.
Prices will be little higher than before.
Basically SD sized Nino heads are available on SD13/SD, Delf boy and other similar sized bodies. As far as I know, Volks old normal skin is best match.
But small color difference could be. Please understand that
the heads were made by a person, not by a major doll company.
