Thanks for the feedback! The last few times I've ordered, I've gotten the E05 (which I almost never use b/c I have the full size, MAC 209 and SK brush) and shadows. I wonder if they send diff shadows or if it's always the same three shades? I liked when they gave travel E25 brushes.
I was looking into the E35, but luckily was able to score some at the CCO. I do enjoy the brushes I do have (especially the Sigmax face brushes...those are so awesome).
I'm still debating on whether or not I should try the F15 (MAC 131 dupe). I've heard they were similar but it seems flatter? The Hakuhodo brush is also another option, but I've never tried that company and am unsure about the quality. Then again, I never owned the 131, so I might be none the wiser re: which is best.
I know they now give out single shadow gifts as well. I'm assuming that they will rotate colors every few months. As far as brushes go Hakuhodo brushes are a dream, there is no need to worry about quality there. Not even sure if I have ever read a bad review about them either. As far as the F15, its not an exact dupe of the MAC 131. The shape is pretty dead on but the density is different. I also find that the synthetic fibers that Sigma uses in their duo fibre brushes are a bit stiffer & are not nearly as soft as the MAC ones. They aren't scratchy & still apply product well, but I find that I grab for my MAC duo fibre brushes when i want to layer product more softly as the stiffer Sigma fibers can pick up more product than desired. I also have to note that the duo fibre brushes from Sigma are the only ones that have had shedding issues for me.
