Part of the MAC Makeup Art Cosmetics Collection includes two Reflects Glitters (Copper and Rust), two Glitters (Gold and Fuchsia).
You can mix in glitter with all sorts of products. I like the Reflects the most for mix-ins, just because it is a finer grade glitter. It’s particularly nice on lips and mixed with lotion/moisturizer and used on legs and shoulders. For the regular glitters, I think they look nice when spritzed into the hair or mixed with nail polish.
Recommendation: As much as I adore the way Reflects glitters look and feel, I find myself rarely using them. All of the glitters are beautiful shades, though they are also permanent at PRO stores, so you don’t have to hurry if you’re on a budget. I also distinctly remember glitters being priced less than pigments, so I’m not sure why that changed.
