UPDATE: I finished my chat with MAC CS and was lucky enough to get a girl who was determined to find out what happened to this quad for me. Here's what she ended up discovering:
Well I hate to disappoint after ALL this but it seems that quad did get mixed-up somehow. It's actually from a collection called Lovely Eyes that launch exclusively in Asia. I am so sorry for the run-around! That's why I couldn't find it in my spreadsheets, etc. It's only in Asian markets.
So I'm really bummed out that the Idol Eyes quad is only in Asia, but maybe it will make its way to the US eventually? Anyway, if anyone does the live chat and gets Maura, she rocked my socks. We were chatting for about 45 minutes while she looked tirelessly for this quad, and she was totally pleasant the whole time! I actually hit the End Chat button not realizing that the survey wouldn't come up if I did that, so I immediately called MAC CS and asked to speak to a supervisor to give this girl a rave review. She deserved it!
