Troll glitter
Color: Brandy-Rose
Do not spray too much! This glitter is so fine that it dispenses easily from the puff part and you can easily make yourself look like Poppy the troll. We had so much fun with this for prom

Glitter with staying power
Color: Rainy-Rainbow, Color: Rainy-Rainbow
Super fun and sparkly, the color is beautiful, it comes with 2 glue tubes with brushes that you use to rub the glue onto your skin in order for the sparkle to stick better and longer, made a heart shape on my arm, dries fairly quickly and washes off easily when you're done with it It sprays a fine layer and evenly, it's great for building on for more sparkle or to just have a light layer Even without the glue it lasts at least a couple hours with minimal shedding and light use, seems to have good longevity With 2 glue tubes, a refill tub, funnel and the glitter spray bottle I feel $10 is a great value considering everything you get with it, Overall I feel like it's a fantastic product and will buy again!

Decent for the price.
Color: Rainy-Rainbow
The color is pretty, the bottle seems to be working well for now. The atomizer pump is so cute and makes me feel super dainty and girly! I love the xtra refill, the funnel and two glitter glues for makeup looks. The glue is good enough to hold the glitter but not too sticky where it leaves a nasty residue. So that’s a plus and it’s easy to wash off. However, the glitter does not adhere or stay in place on dry skin. I’m assuming it’ll be great to spray on the body if you have some type of oil in for it to adhere too but haven’t tried it yet. Will update next weekend.
