I was super excited for these brushes because I follow Pixiwoo and love their videos. I ordered from Ulta the Core collection ($16) and the stippling brush. (10). Honestly my first impression upon usage of these brushes was, eh. I was a little let down because they are not as soft as I wanted them to be. The Core seemed like a good option because it contained brushes I thought I'd use the most, detailer, pointed foundation, buffing, and contour brush. I had seen Pixiwoo and Pixi2woo using the buffing brush for foundation as well as the stippling brush. However, they both fall short of expectation. The buffing brush sort of just phloophed my mineral makeup around, I've found the HD rounded buki brush from Sigma works the best so far for me. The stippling brush is just ok. I just use it as a back up brush if I'm out of clean synthetics for cream product application. The only brush that is worth it for me is the contour brush. It's soft, and is good for a light application of contour powders and highlighters, blush. However if I want to build up intensity, I find I have to keep loading up the brush.
