One late night in February I was lurking the depths of eBay and ended up buying three sets of different make-up brushes - one including these RT dupes. (Here's the little link for where I bought them from). Upon arrival they were all in shape and didn't have that nasty chemical smell that some eBay brushes have. They also had a luxurious feel, not only in the way they looked - but in the way they felt (they're super duper soft). They cost $11 for the set, each brush being $1.50, which is such a steal.
100 Arched Powder: Ultimate powder brush. Personally I prefer a light swooping of powder so this is ideal if you want it light. I find my powder never goes on cakey with this as it isn't a dense brush.

 101 Triangle Foundation: I actually own the real version of this - shout out to my brother for being awesome and buying me an A++ birthday present - and the real thing is very similar. I would say the legit one is of obvious higher quality. That being said I think this brush is a pretty damn good for a dupe. Foundation applies lovely with this.

300 Tapered Blush: Despite this being intended to be used as a blush brush I use this for highlighter. Could definitely be used for either though! One of my favourites from the set.

301 Flat Contour: I use this to both contour and bronze. The shape is excellent for getting under those cheekbones.
200 Oval Shadow: It's meant to be an all-rounder eyeshadow brush but personally I prefer it for highlighting smaller areas such as under the eyebrows and cupids bow.

201 Pointed Crease: As you can probably tell from the colour of this brush I use it for ze eyeshadow crease. It's quite dense but it makes it oddly easy to blend in everything together.

202 Angled Liner: Is intended to be used as eyeliner brush but I prefer using it to apply eyeshadow to my lower lash line. That may be just me though - but I think it works well for that.

Verdict: I will admit I have noticed that the largest brush of the set (powder brush) is prone to shedding slightly but aside from that I haven't noticed shedding from any others. I think that these are fantastic eBay brushes. Ebay can be hit and miss - but these are the ones that are worth the buy. They are of high quality, feel luxurious, and have a great range of brushes. *heart eyes emoji*
