All four colours can be used as eye shadows as well, but I tend to just use them for my brows. I use the bottom two colours on my brows to make them appear fuller and less sparse. I feel like the powder works brilliantly at filling in any gaps in the hairs and makes them match my hair colour more. They are pretty pigmented, so you have to have a light hand when applying. I like to use the Real Techniques Detailer Brush when defining my brows rather than the little brush that comes with the kit. However, for on the go, this would be fine. The mirror is also of great quality and is great for applying up close, as if you are short sighted like me, this can be pretty hard. Overall, I would recommend the HD Brow Kit.
