The Starter Kit ($15.99USD) and Shading Brush ($5.99USD) pretty much covers the brushes needed to do the eye from a basic look to a smoky look.
There are five eye brushes in the Starter Kit: Base Shadow, Deluxe Crease, Accent, Pixel Point, and Brow.
The Base Shadow brush is a fluffy brush that applies a wash of color onto the eyes with the tip. Since it is soft and the tip splays out, this is useful in applying dark colors softly. It pretty much works as a great blending brush also. This is one of the brushes that gets the most use for me.
The Deluxe Crease brush is a firmly packed round brush and too big for a precision application of just in the crease. This is more for blending the crease area or applying color all over the eyes. I am not really a fan of this brush because it is just round and too big.
The Accent brush is a small brush that I reach for
all the time because of my small lid area and my love for smokiness. This one pretty much does the job. It can be used for any detailed work or look around the eyes from highlighting the corner to smudging an eyeliner. A very handy brush.
The Pixel Point Eyeliner brush is brush supposedly used for eyelining. It is slightly firm but not pokey, soft enough for some who have a sensitive lashline. I am not a fan of this brush because I find the hair too long and the width too wide for any precision detailing of eyelining. I can't really find any use for this brush too much unless I am trying to "dot" on dots on my lid; the tip helps for that. I suppose you can use it to apply cream colors only in the corners of the eye or concealer. Not a favorite and gets the least amount of usage.
The Brow brush is a thick one and firm yet soft enough where it doesn't feel like pins sticking into your forehead as you apply color. I admit I don't use this one for the brows because I find it a bit too big on the surface area. It can blend more than it can apply brow color precisely. However, instead of using this as a brow brush, I find it useful in "cutting the crease" or any form of application where a line is needed. Just use the tip to draw a line and blend.
The Shading Brush is sold separately from the rest of the brushes. This is the usual all around eyeshadow brush that you see in every line. It is used for every eye shape and can be used for any texture of shadow. If you just want one eyeshadow brush, this is the one to get.
There you have it, the brushes I bought. Would I get more? Maybe. I do like synthetic brushes because of their ease in cleaning. Technology has changed how synthetic brushes are made and they can be as soft as natural hair brushes. Are there better quality synthetics out there? You bet, some even feel like real hair but are just as expensive. Economically, these are a great line of synthetic brushes that are easily accessible (for some) and should not be overlooked.
