After doing a little web surfing *enter Beach Boys music here* I found out that the owner of OPI is the founding member of the Nail Manufacturer's Council. This explains a lot.
Well, that's it for my "industry insider" tidbit for today! Hope this found you well-polished and left you as intrigued as it did me. This doesn't change my love for either brand, but does help put some puzzle pieces together (i.e. color dupes, new finishes across multiple brands, etc.).
