OPI Products, branded as O·P·I, is an American nail polish manufacturer headquartered in North Hollywood, California and a subsidiary of Coty, Inc..
OPI, originally named Odontorium Products Inc., was a small dental supply company purchased by George Schaeffer in 1981. Shortly after taking over the company, Schaeffer was joined by Suzi Weiss-Fischmann, OPI’s Executive Vice President and Artistic Director. Schaeffer and Weiss-Fischmann partnered with R. Eric Montgomery, a biochemist, and created an acrylic system that Schaeffer sold door-to-door to local nail salons. They closed the dental sales and focused entirely on nail products changing the name to OPI Products Inc.
