What does OPI Stand for? OPI stands for Odontorium Products Inc. It was initially founded as a dental supply company in 1981 but later shifted its focus to the nail care industry. Today, OPI is known worldwide for its high-quality nail products and is a leading brand in the professional nail care industry.

Why does OPI only sell gel to salons? OPI's gel products are created with salons and nail technicians in mind. They are made for professional use only and should only be applied by a qualified nail technician. Because of this, all OPI gel products are sold directly to professionals.

( Shellac is just a Brand of a Gel Polish blend) so Shellac and OPI Gel Polish are the same thing! CND Shellac/OPI Gel Polish is a blend of gel and nail polish. Because it is like a polish, it can't be used to extend your nail. Because it is like a gel, however, it does add strength and durability.

One of my favorite things about OPI is its ability to self-level. You could glob the nail polish on and it would still spread out evenly. Another thing that I found that I loved about OPI was its smooth application. The formula is not goopy at all, and dries smoothly and quickly.
