This is a set of 2 mind control collars which were used by Dutch & Khlyen in the series finale, when the Lady forces them to fight each other. Since these are the stunt versions these would have been used during the actual fight and not during the conversation sections.
Both collars have a cell battery compartment which lights up the front of the collar blue.
Khlyen's collar which is slightly larger, is also made of a softer rubber material, whereas Dutch's collar is a much harder rubber.
Both connect via a magnet clasp.
