Waste of money
Size: 1PCS, Color: Green
Barely noticeable! I bought the green glitter and let's just say there's Very little glitter! Pretty much non-existent. Definitely not worth $10 and It's not returnable. For $10 I would have expected something noticeable

Very pretty.....but it spreads.....a lot
Size: 1PCS, Color: Holo Silver
I put this on my cosplay wig, but I had to take it outside to apply. This gets EVERYWHERE. I'm still finding glitter months later. It is easy to apply and dries quickly initially, but it just spreads everywhere.

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.

Love the way this makes you shimmer and shine. It's absolutely beautiful.

This stuff is bomb! It is so good. It looks so good on the skin and it doesn't have a bad smell. It smells actually good. I would continue. I will continue to purchase this product. I love it that much!
