These are some synthetic brushes that I bought for a couple bucks on a whim... Strangely they're my most used foundation brushes!
I love that they are easier to clean, they don't shed, don't absorb too much product.... And application is easy and smooth. Usually I try to avoid over washing brushes but these have stood up through a lot of washes and when they do wear out, I wont hesitate to replace, and happy they won't cost me a bunch. I don't usually go the cheap route for brushes either but I promise, these are worth a try!!
