These brushes are made pretty well and are very inexpensive. I have never had any shedding issues with them they are very accessible, Ulta carries Morphe brand. They are sold individually and in sets.
This little guy is one of the best makeup tools I have ever owned. This is perfect for blending your foundation and concealer. You will never know how you lived without this! I use mine by wetting it in the sink and squeezing out the excess water then I roll it into a towel to ensure it is only damp.
