What does O.P.I. stand for?

It is "Odontorium Products, Inc." that makes the nail polish.

So it should be pronounced as O-P-I! Hope that helps!

I say oh pee eye

Its pronounced oh p i.

Lol i never thought of it as oh pi haha

haha, it's literally O.P.I, oh pee eye.

(:

oh pee i

because the other way would kinda be spanglish

I've heard people say both, I personally say all three letters OPI.
