Royal Plastics Corporation

A Cincinnati, Ohio-based pressing plant founded in 1946. Records manufactured here are often called "King Custom Pressings." The plant operated in tandem with the Syd Nathan, A.E. Slapin, Samuel A. Rubinstein, and Howard Kessel. In addition to its work with King, it also offered custom pressing services for many other clients from its founding until it ultimately ceased operations around the early 1970s.

Royal Plastics pressings can sometimes be identified by an elaborate "𝓡" symbol stamp or a small "R" etched in the runout grooves.
