Pretty, does come off easily
Color: Holo Silver Glitter Spray（2oz）
Works well. Glitter does come off pretty easily. If on clothing you can easily pat it off of you which for me was a con but for others might be a pro.

Spray bottle was defective...twice!!!
Color: Light Pink Glitter Spray（4.05oz）
Product itself was awesome...when it worked. The design if the spray bottle is awful. The first one I bought only sprayed once when we first got it but then the spray piece didnt work anymore and only sprayed air. I got a refund on it after I told them. I thought maybe I just was unlucky and got a defective one, so I bought another. Same thing happened, only the push down spray part got stuck after using it once and it just sputtered out air and clear liquid! I was able to get a refund a second time, but I'll be looking for a different company to buy from. Sad cause the one time it did spray out some stuff correctly it looked beautiful.
