Irontech make very stunning faces. I have a small collection of them myself, they are mainly hard silicone heads with movable eyes, movable eyes are very important to me.
Something I wish manufacturers would state more clearly is whether their doll heads eyes are movable or not and which heads get mechanical moveable eyes, also a little more clear about the options and what those options affect.
I had a conversation with Irontech back in June whilst placing my doll order, I would have liked to order the S40 head with mechanical eyes and movable jaw
, the information I got back was 'If you want the active oral head. The eyes can't move. The mechanical eye mismatch. The hardness of the Active oral head is somewhere between soft and hard. To some folks that is very imported information. I decide to forsake the moveable jaw, because I want the mechanical eyes.
