I've had my Everyday Minerals Flat Top Brush for more than a year. I am not a big fan. I prefer long handle brushes because they look better. Also, this brush does not fit nicely in my brush holder because the handle is too thick. It doesn't stand properly and looks weird with my other brushes that are taller. However, this would be perfect for travel because it's only 4 inches long.
The bristles are synthetic and are the softest and densest I've ever felt. It picks up a lot of powder, and would be best used for mineral foundation. However, it's too hard to buff in a circular motion. You really have to work it in because the bristles are super dense and are too long (1.25 inches). Also, just like my Everyday Minerals Long Handled Kabuki brush (review), the product gets deep down into the bristles and gets wasted.
Another issue I have with this brush is that it takes forever to dry. After I washed it, I used a paper towel to absorb as much water out of it as I could, but it still took about 14 hours to completely dry.
It was $10.00 when I bought it at EverydayMinerals.com, but I noticed they raised the price to $11.00. I finally decided to sell it on Ebay. Good news is that I sold it for the price that I originally bought for it. =)
