Amazon has the Susenstone 20-pc Makeup Brush Set for just $2.00 with $2.50 shipping, making the whole set only $4.50 total! I bought a very similar set of the same brand a while back, and I really have nothing but GOOD things to say about them! They’re pretty good quality for the price, soft, and there are LOTS of different brushes in the set. I use them almost every day for makeup, and I even have a few that I use for nail art. Even after being dipped in acetone countless times, they still hold up!
If you’re looking for an affordable makeup brush set, I highly recommend these!
