Milani Jewel FX in Hot Pink is a mix of two hex glitters suspended in a nice clear base. So one type of glitters are distinct holos. These are brilliant and although they can be mistaken for silver from a distance, they are magnificent. Because of their larger size, you really see the reflections of rainbows varying from piece to piece. The other shade is what I imagine Milani feels is a hot pink whereas I see it as more of a dark pink bordering fushia in certain angles. These hex glitters are at what I would call a larger size, but that is just my take on it.
Application is like any larger size glitter, some assembly required. You always have to do some wiggling and such. I do love the clear base though, it was just the right consistency!
