The brush is nice, flat and wide, but it feels too close to the cap: the stick between the end of the white cap and the bristles of the brush is really short, which made the whole thing hard to maneuver with precision for me, and you'll see in the pics that I painted my cuticles accidentally on several nails.
Morevoer, the texture is on the thicker side, not flowing quite as much as I wanted, but it's very pigmented and nicely opaque in 2 coats. It dries (taking its sweet time...) to a semi-matte finish, so you'll want to use a glossy top coat if you want a shiny finish!
In the bottle, it's a gorgeous plummy violet with this amazing, strong blue shimmer, but it doesn't translate quite as stunning on the nail. It's still a very pretty medium purple with blue shimmer, just not as breath-teaking!
Overall, the quality here is not perfect, and I'm slightly disappointed with the result on the nail. For $9, I don't regret buying it, and I know I'll still wear it often, maybe with a shimmery blue top coat to add depth!
