A variety of glitter!
This brush set is all about sparkle and glitter. There are three different styles, two of which have multiple variants:
"High Sparkle" - Sharp and bright, works well on its own or as an accent added to the others
"Mist" - Sparkles with a dense, almost foggy effect. Comes in two shapes (round, star)
"Sequin" - Translucent glitter raining down. Comes in two shapes (round, hexagonal), each of which has a smooth version, a holographic version that changes with your brush color, and a preset bright holographic version
As is often true with sparkle brushes, using them on a light emitting layer (such as "add (glow)") gets brighter, shinier results!
