Horrible. Do not recommend.
Color: 1PC Glint-Rainbow
Horrible! Do no recommend. The container is super small and it doesn’t spray well. It literally falls in clumps and is very wasteful. I would have returned it had I not been in a hurry and needed something quick for dance recital weekend.

Tiny. Expensive. Dont bother.
Color: 1PC Glint-Rainbow
I just paid $8 for ONE BOTTLE THIS SMALL??? and I hate the photos shows two bottles. Its like they want you to buy it thinking you get 2 for the price if you dont read the description. This is the smallest bottle. Not worth it for the price

Glitter bomb
Color: 1PC Glint-Rainbow
This dries quickly and looks very pretty, but beware the application process is iffy- I get glitter bombed every time I pick this up. It could be operator error- but I can’t control the application at all.
