Accessory Pack - Ghost Light (Unproduced)
From VitruvianFACTS
Note: This set was a test run for the Ghost Light Glow in the Dark Accessory Set, but was ultimately not produced in that format. Instead, Boss Fight Studio has sent it along in many of their customer offerings, making it available to their customers, though not in the format that it was originally intended.
The final, produced version of this item can be seen here: Accessory Pack - Ghost Light.
