Not very much dispenses with pumps
Color: Glint Rainbow
This gives out very small puffs of glitter when depressing the pump. The glitter is as expected, but it would be more efficient to just open the dispenser with how little this pumps out. I'll probably just use this for crafts instead of body and hair. It doesnt really stick either because it is a dry powder

Fine, dry glitter in a puff spray bottle
Color: Glint Rainbow
This works well if, and only if, you know exactly what it is and if it'll work for your application.
This glitter comes with no adhesive or stickiness in it. It is not like a glitter stick, or glitter makeup. It is dry glitter in a spray bottle. The spray pattern is very narrow, so if you want to spray it onto a piece of paper or you body, it will show up in a clump. It does not have an airy spray pattern.
To use this, you need to add some stickiness to the surface you want it to stick to first. Something like glue on paper or some sort of sticky thing on your skin that won't sink in. If regular lotion sinks in, the glitter will just fall off. So petroleum jelly or something that sits on top works best.
Also, if you want it spread out instead of in little clumps as it comes out of the spray bottle, you'll have to move it around manually. On some level, to be entirely honest, I'm not sure this application method is better than loose glitter. With loose glitter, at least I can manually sprinkle it and not get a giant blob like with the spray. Also, some little bits get loose with the spray, and loose glitter in a house is just asking for forever glitter.
I'm deducting one star simply because the spray delivery mechanism isn't very useful, and can actually be a liability. Unlike some spray glitters with propellant and adhesive that are more like spray paint and have a more spray paint application profile. This manual puff method just doesn't work well with glitter.

Dry glitter, not glue
Color: Glint Rainbow
This is dry glitter, not glitter spray. Will need glue for it to stick but it’s very pretty.

Fine holographic sparkle with smooth and even application
Color: Glint Rainbow
I tested this glitter powder several times over about two weeks while using it on my hair and along the cheek area for festival style makeup looks. The shimmer particles are very fine, which helps create a smooth reflective effect rather than chunky glitter.
The applicator releases a light dusting of powder, which makes it easier to control how much product is applied. I found that building it gradually works best, starting with a light layer and adding more for a stronger sparkle effect.
The holographic finish reflects different tones depending on the lighting, shifting slightly between soft rainbow colors under brighter light. It looks subtle indoors but becomes more noticeable and reflective in direct lighting or outdoor settings.
During wear, the glitter stayed in place for several hours with minimal fallout when applied lightly. I noticed that applying it over slightly set makeup or hair helped it adhere better and reduced loose particles.
With its fine texture, controllable application, and noticeable sparkle under different lighting, it delivers a versatile glitter effect for creative makeup looks. The quantity of the spray was nice and it was durable under the sun too.
