Shown here in 14mm and worn by a Planet Doll Riz.

Shown below on a Kaye Wiggs Abby in 16mm.  There is the tiniest bit of eye gap, but not bad.  If this bothers you, Abby wears a 17mm in Masterpiece soft glass perfectly, xoxox.

I just love this eye for quality and cost.  Available in 12mm, 14mm, 16mm, 18mm and 20mm.  These are a polymer acrylic handmade by the folks at Masterpiece Eyes.  Please choose your size from the Options pull down at the time of purchase.  All sizes cost the same amount.
