Great long lasting glitter.
Size: 1PCS, Color: Holo Silver
Wore this to a part and I was happy with how glittery and gorgeous the glitter was. Was easy to use, sprayer evenly and the quality is nice, lasted a good few hours after application. Functioned well on both clothes and skin and left minimal sticky residue. Great product.

Not the best
Size: 1PCS, Color: Holo Silver
This product is good for adding some glitter and glam but it comes out too fast. It also hardens the hair as well. The color is nice.

Pretty
Color: Light Rose Gold Body Glow
This stuff has a strong scent. Sort of beachy, sunscreen smell, which is not my favorite. It is definitely shimmery. I used this for a hawaiian themed party. It was pretty! It dried down fairly quickly. I did place a towel down in my car before I got in it just in case some of it came off the back of my legs and got all over the seat. I wear black pants to work most days, and didn't want a glitter butt every day.
