Do not buy this
Size: Medium, Unit Count: 2
This is not a good product ! Whenever I put products on my feet and put them on the socks they were on for about 2 to 3 minutes I had to keep adjusting them on my feet then they started ripping

LOVE IT
Color: Pink
It's STRONG. Tap lightly and so much sparkle comes out. I keep it in the box it came in and it's perfect. Will be rebuying.

LOVE FOR GOING OUT
Color: Pink
Love!! I put it on after the shower. It has no smell and definitely worth the price. Might need to poke it a couple times over time but other than that it’s great!

So cute!
Color: Pink, Color: Pink
Adorable puff that puts out plentiful sparkle (or a modest amount with only a few pats if you don’t want to glow in the sun like me).
