Great stuff!
Color: #3 Rose Gold
Trying to give 4.5 stars. It’s phenomenal! My only .5 is that is absolutely does rub off on clothing. I’m going to a party tomorrow and I’ll try using setting spray after application.
I love it though. Light weight, no odor and shimmer you can use on body, hair and even accessories!

Beautiful, Subtle, Long Lasting Sparkle
Color: #3 Rose Gold
Sprays easily and seems long lasting, (stayed on for more than 3 hours of light household work). The glitter is very fine, and that’s exactly what I wanted, it is not visible dots or shapes- my arms just sparkled when I moved them and with the changing light. Feels like nothing is there. Nice!
Doesn’t feel especially moisturizing, but hasn’t dried my skin out either.
