OPI Fly vs. Hard Candy Frenzy-Dupe Alert!

Hi everyone! Today I've got a dupe alert for you. These two polishes have been sitting next to each other for a few months and I finally tried them out on the same hand to compare. OPI Fly and Hard Candy Frenzy are extremely similar. OPI Fly is just a tiny tiny bit more green than HC Frenzy, but to someone who didn't know I was wearing two polishes, it would be practically impossible to tell.

Has anyone else spotted these two as twinsies?
