So pretty!
Color: Late Autumn
This shimmer is beautiful! It applies smoothly and evenly and it sparkles absolutely beautifully. You can do one spritz for a very light coverage or a few to really glow! I love the applicator - makes me feel fancy. It was a little bit sticky at first but it dries quickly and isn't sticky after that. It's a really great product to brighten up your look. Highly recommend!

This is such a fun little product.
Color: Diamond White
This is such a fun little product. The shimmer is really pretty and fine, not chunky or glittery in a bad way. It gives a nice glow without looking overdone. Super easy to apply and a little goes a long way. I’ve used it on my face and collarbones and it looks great in different lighting. For the price, I’m honestly impressed.

Glitter Puffs
Color: Late Autumn, Color: Late Autumn
*Poof* and then there was glitter. Boko Highlighter Powder Spray, Body Shimmer Spray for Glitter Highlighter Makeup makes it as easy as squeezing a bulb. The biggest part of the assembly of the product is to male sure you remove the plastic cap and the rubber tipped end. If you miss either the spray will seem to not work.
Once properly set up the powder spray bottle only takes a modest squeeze to dust the skin with instant glitter and glory. I love the look, the easy to use spray, and the bottle itself which has a simple but elegant feel to it!

Extremely fine shimmer- the air bulb works well for application- Even and controllable
Color: Late Autumn
This is a great way to apply a very fine sparkle. The shimmer is very very finely ground and it sprays out evenly with this air bulb. It does have a lid so there's no chance on it getting everywhere unless you leave the lid off. It also comes with a little plug in the hole so there's two mechanisms there to keep the glitter in the bottle when not in use it's very easy to use and apply and the spray pattern is very even.
I got the golden shimmer which looks great with a tan or if you have warmer undertones in your skin.
It doesn't require any sort of setter or glue + doesn't have any fragrance. It's a small bottle so it doesn't take up a lot of room.

Great find!
I used this on a prom bouquet and it came out beautiful. Soft dainty sparkles for the perfect shimmer. A convenient small aerosol container that I gave to my son’s girlfriend in case she wanted to touch it up or use it herself. I love the fact that it’s still stuck on my crafting desk. Very affordable and it served its purpose plus some!
