I thought I would talk you through the brushes and what I use them for, as the W7 website doesn't have a large description on the set. Starting from top left going across, down to the left through to the right.
Lip Liner Brush
This small and thin brush will make light work of defining your lip line with lipstick. I don't bother using a brush if it's a nude shade, but for super dark shades like Charlotte Tilbury's Glastonberry, I like to carefully apply it with one of these style brushes for a crisp and defined line.
Small Shadow Brush, Medium Shadow Brush, Large Shadow Brush
It's a shame that the shadow brushes are all the same but in different sizes, it would have been good to see one like the MAC 217. You can swipe eyeshadow easily across your lids with these brushes and they are the softest of the set.
This was the brush I was most excited about using, I'd always seen them in make-up artists sets but never bought one. I currently use this one for highlight, it's great for a light dusting and doesn't deposit too much product.
I will always have one of these combs handy, they are great for brushing out clumpy mascara. It's a simple brush, but a good one.
This diddy brush is ideal for precise eyeliner, I use this with my L'Oreal Gel Liner for a defined cat eye flick.
Realistically this is one I would throw away, no one likes these sponge applicators.
Angled Face Brush
The angled shape of this brush makes it ideal for contour as it gets right into the hollows of your cheeks. It is a little scratchy though.
I have been using this for pin point powdering, I just sweep the brush with powder on over my T-Zone and leave the rest of my face powder free.
Angled Eye Brush
Sadly this isn't the most defined angled brush so I wouldn't recommend it for gel eyeliner. I suppose you could use it to blend eyeshadow out across the lash line for a smoky look.
I don't know what I'd do without a spoolie in my kit, perfect for grooming my unruly brows.
Overall, the set is of cheap quality but it does only cost £12.99. As for the quality of the brush hairs, sadly they aren't great. I think the Shadow brushes are the softest, but the Powder and Angled Face Brush feel so synthetic and scratchy.
To get a whole brush set for £12.99 would be great for beginners or a younger audience but high street brands like W7 really can't win over Real Techniques. I wouldn't recommend purchasing the set. I would personally recommend spending a tiny bit more for Real Techniques brushes.
