Authentic Skeleton Repair Kits are medical items used to heal cutting damage on robotic body parts. These kits can be stored in Storage: Robotics. The name is somewhat misleading as the standard Skeleton Repair Kit is superior both in weight and charges. This likely implies that the Western Hivers gave their inferior product a fancy name in order to boost sales.
Generic members of the Anti-slavers can be found carrying these. This might suggest some trade relation between them and the Western Hive.
