To achieve this, eyelid panels with false eyelashes along their lower edges were stuck behind the dummy mask's open eyeholes. Closed eyelids would have been a pointless addition to the hero mask, or a stand-by mask intended for possible use by an actor. Only the dummy would have been given closed eyes.

These beads turned out to be a vital clue in tracing the early history of this Mr Sin mask, and pointed to further evidence of its origin as the mask worn by the dummy prop.
