Maybe it will arrive. Or maybe not.
Color: Gold
Smells great, but never on time. This time I didn't receive at all, for what I needed.

This is cute. Bought it for a special event for myself but my little girls are obsessed! Love that it comes with two refills. Good value. Love the cute little delivery system.

Sparkling
Color: Silver
Nice glitter. Washes off cleanly and easily but stays put during the night.

It will shine/glitter up your world.
Color: Silver
My daughter loves this. She has me buy her one every Christmas and uses it to shimmer up everything! Mists out fine particles of glitter as a big poof. It does tend to get everywhere. More even when applying, unlike the brush on applicating ones.

Absolutely good body glitter.
Color: Green
Applies ever so prettily and looks gorgeous against the skin. Easy to use and sparkles for ever. Will stick better if skin is a bit slict, wet, or moist. But still stays on dry skin.
