I received a few emails on Sigma brushes. First off, I do not sell nor own Sigma brushes. I'm just like any other consumers who just bought them for the sake of their price which is a fraction of MAC's.
Secondly, some asked if I got SS188 brush. And I have it, until just recently...
The SS109 (the top one) is for one of my spree members and I only owned one SS188 (and not all four, mind you -_-).
Here's a little brief summary on both SS187 and SS188.
The length of both brushes are slightly different.
The brush shape is obviously different as well.
And the density of these brushes.
A more clearer pic...
SS188 retails for $14.
I saw some comments on people says that these Sigma brushes do frayed a lot. But for mine, they are still okay. Just like the way I got them in the first place.
As for the SS188, I love it! Soft and silky feeling on the skin. No crazy bleeding like the SS150 and does not shed too! Definitely recommend this one as an alternative from MAC's 188. :) BTW, I went to test and "feel" Etude's skunk brush since a lot of bloggers have raved about them. And I think they are not really comparable with Sigma's 188 or even SS187. The feeling of the brush is just different. Wait til I get my hands on that Etude's skunk brush and I'll do a photo comparison. :)
BTW, MAC's Color Craft collection has their 131 brush as well, I'm still thinking whether if it is worth the splurge on them. What do you think? :P
PS: Here's the 12 Brushes, the complete set without the brush roll from Sigma. :)
