So I decided to search eBay and found a nice looking set of 5 brushes, here's the eBay title and description:
5Pcs Makeup Brushes Thin Different Advanced Artificial Fiber Cosmetic Black New
Precision Flat™: Stipple concealer on sun spots, blemishes, and other small imperfections.
Precision Round™: Apply eye shadow base or primer onto the lid.
Precision Angled™: Apply product to areas such as the sides of the nose and the hollows of the cheeks.
Precision Tapered™: Exact placement of concealer in harder to reach areas such as around the eyes and nose, chin, and around the mouth.
Precision Flat Angled™: Use for precise application of concealer products anywhere on the face. Works particularly well around the eyes and nose.
The brand of these is SixPlus or 6+, and I ordered them 6/02 for $12.99 plus $3.99 shipping. These were shipping from China, so boy was I surprised when on 6/10 I already had these in my mailbox!
I am really impressed with the quality of these! They are so super soft and don't shed. A few of them, the ones with longest bristles, are more fluffy rather than stiff/dense, but I don't really find that problematic since in some cases you want a less stiff brush for blending.
Overall, I am really happy with these especially considering the price.
Here are some pics of the brushes:
