SPFX Zombie Mask

SPFX Masks make some of the most impressive masks I've seen. They use silicon which allows the mask to form fit over the head but also allows facial movement, talking (and eating) and expressions.

For commercial haunters, they can eliminate the need for make-up and are fast to put on and take off. This YouTube video show the Zombie mask in action.

They have several different designs. I particularly like the "Old Man" mask. 2 or 3 new characters are added each year and the attention to detail is simply amazing. These masks are however pricey. Last year the masks sold for $200-$300 per mask but this year the prices are closer to the $500-$800 range, depending on the design.
