In third season episode Metamorphosis, Will finds himself undergoing a reptilian transformation, after being accidentally infected with spores from a predatory plant-animal hybrid creature found in Hollow Earth. When mutated Will escapes the Sanctuary, Magnus, Kate and Henry track him to an abandoned warehouse, where they use these darts, filled with a combination of a specific anti-mutagen and a powerful sedative, to both subdue and cure him.
Metal darts with red tailpieces, carried in custom leather forearm cuffs. Some of the darts have spring-loaded hypodermic needles to simulate skin penetration. One has a shaft that has been partially cut, presumably to allow for a breakaway effect although this is not seen in use. Others are missing the distal shaft and needle entirely, and only seen carried within the leather cuffs. Includes the black Pelican carrying case also present onscreen.
