Soft, durable, least shedding bristles, overall sleek design, grabs just the right amount of pigment whether natural or synthetic fiber [though this depends on you too ;)], fairly affordable (great investment), and easy to clean… these are all the things I love about my Sigma Beauty brushes :). I have two of their sets (use them daily for nearly 4 years), their full-size and travel-size; it’s ideal to have two different sizes. My only small qualm is with their eyeshadow brush (Pencil E30) which I use for the outer corners of my eyes; personally I would benefit from a smaller, stiffer brush since I don’t have the deepest creases. Most people don’t have to be concerned with this… To be fair, I may not be using the best brush for what I’m trying to achieve so I’ll have to look into another Sigma brush. Honestly they are the best brushes I’ve ever owned and trust me, I’ve owned a good number of them from many well-known brands.
