This is the Core Collection ($15.99USD) which consists of four brushes for sculpting and correcting the face. I find this set more useful than the Travel Essentials set because these brushes complete the face or create the foundation for the color products. Here are the brushes in this set.
The Buffing Brush is a round brush with a slightly flat top with beveled edges making it slightly softer than the completely flat top brushes being sold. This one is dense but not as dense as other brushes I have in this shape but it does its job well for buffing mineral foundations, applying cream blushes, stippling cream foundations, etc. This is more firm than the Multi Task brush found in the Travel Essentials.
The Pointed Foundation Brush is smaller and less dense than the Essential Foundation brush. This one has a more pointed tip to allow application in the smaller areas like the corners of the nose, eyes, and mouth. Thinner in thickness, it is more for the precision application of foundation and less on the blending. However, I do find it great for blending out concealer. Basically a brush that blends product in a small area.
The Detailer Brush (which mine turned out to be slightly bent) is a brush that resembles a lip brush. It can be used for lip products, concealer, eyeliner, etc. It is a small filbert shaped brush that is pretty useful for pretty much everything. IF it weren't bent, I would probably like this one a lot more!
The Contour Brush is a round brush with a rounded cut on the hair giving it a point at the tip which is useful for applying contour in the hollows of the cheeks. However, I use this one as a blush brush because the tip allows for precision placement on the cheeks without it splaying out in all directions. It can also be used to apply highlighting powder for a touch of glow.
All these brushes, like I mentioned in the previous post are synthetic which makes them vegan friendly. I like synthetic brushes because they are easy to clean and dry quickly. In between the thorough washings, I just dip my brushes in 99% isopropyl alcohol and swipe on a towel. If you want a set of synthetic brushes for an economical price, these are the ones to get.
