You can find these in our webstore either with the full mask unhinged (needs a V-hinge), or just the top half for people wanting them for a headdress or what-not. [link]
3 or 4 cm eyes will fit; no jawset needed.
Fits up to a 23" head
These is a tutorial on how to hinge this mask if you want to do it yourself on our youtube. [link]
