C-3P0 Case Clear Plastic Mold Test: It is believed that this mold test was for the ROTJ C-3P0 case since it is made of hard plastic, required for vacuum metallization. However, the sculpting on this case differs from the production C-3P0 case, since there is less detail on the eyes and top of the head. There is also no copyright date stamped anywhere on or inside the case.
