Sigma Makeup Brushes - First impressions

When it comes to creating a masterpiece, the saying goes that you're only as good as the tools you hold in your hand - and well, if this isn't a saying, then it damn well should be! You're never going to recreate the Mona Lisa with a trowel and a toothpick - unless you're a genius, in which case I'm all ears for a few tricks, and with all the will in the world, you're never going to apply your slap to the best of your ability with shoddy brushes. 
Makeup brushes are often overlooked, with people preferring to splash their cash on the main ingredients, myself included, but if you're going to shell out your hard earned cash on makeup, you want to ensure that you're reaping the rewards from a good, clean application. This is where your brushes come in. 

After doing a bit of research online, I decided to give Sigma a go. My brush collection has never been a particularly outstanding feature of my 'kit'. I own a few MAC brushes which I enjoy using, and a couple of eye shadow brushes that I picked up in Qatar which are usable and get the job done, but don't wow me. I briefly considered expanding my MAC collection; however I was swayed towards Sigma, mostly due to the flat kabuki brush, (the far right in the picture below.) I've read a number of positive reviews online regarding the flat kabuki and its ability to apply flawless foundation and I guess curiosity got the better of me. 

Here's what I ordered from left to right:
- Sigma Blending Brush E25 
- Sigma Eye Shading Brush E55 
- Sigma Large Fluff Brush E50
- Sigma Small Contour Brush F05
- Sigma Flat Top Kabuki Brush F80
So what are my initial thoughts? I haven't tried them out with actual makeup yet, and I almost feel like I don't want to because they look so perfect sitting on my dresser, untouched. Is that sad? I'm going to say yes; however they feel incredibly soft and, surprisingly, much more weighted than I anticipated, especially the two larger brushes. There's nothing worse than a flimsy feeling brush. I've also had a fair ruffle of the fibres and the fall out is minimal, in fact, I experienced greater fall out with my two large MAC brushes - but I guess time will tell with this one. 
They're good looking brushes too and it's easy to spot where Sigma got their inspiration from. Let's just say that they don't look out of place sitting next to my MAC brushes. I opted for chrome ferrules, (the metal bit that holds the fibres in places) but Sigma also offer their range of brushes in copper and 18K gold too. Fancy. Each brush features the Sigma logo engraved into the ferrule as well as along the handle; which also contains the brush name and number. Handy if you're a bit of a novice and are likely to forget what each brush is and what it should be used for. 

As it stands, the jury is out on these just yet as I'll need time to get to grips with them and see how they shape up being put to use; however first impressions have been good ones and I really hope that these brushes pull their weight. Watch this space for a more detailed review soon.
I ordered my brushes via Beauty Chamber and you can check their website out right here. 
Do you own any of the Sigma brush range and if so, what are your thoughts?
