Comes with a brush which is not a horrible quality but you'd probably be better off using another brush.
Swatched using the brush provided. Can't really see the shimmer, but there was specks of shimmer everywhere on my arm!
The shiny particles (shimmer?) are quite small, and not chunky. I think this would be a great every day highlighter, if I was to wear highlighter daily myself. I tend to stay away from shimmery products for daily wear because they always ends up ALL over my face.
