So, with my last order I purchased the mini italian badger travel set. The main reason I decided to purchase it was because I really wanted to have a travel sized dome-shaped powder brush. To my dismay, however, the powder brush with the thicker handle was tapered and the blush brush with the thinner handle was dome-shaped. I brought this to Kathy & Steve's attention (with pictures), and they sent out another set for exchange assuring me that the brushes would be the proper shape. Unfortunately I received another set with a tapered powder brush and a dome-shaped blush brush. I sent them an email saying I would happily send both sets back in exchange for a proper set. Instead they have offered to let me keep both sets for the price of one. So just be weary of this before taking the plunge and ordering it... the shape of the two face brushes are not what is pictured on their website (they are reversed in shape -- a tapered powder brush, and dome-shaped blush brush).
This is not to say that they aren't decent brushes. While I am disappointed that they did not turn out as what is pictured on their website (in my opinion, the two face brushes are falsely advertised), it's not a bad set of brushes by any means.
I tried applying mineral makeup with the tapered powder brush and got good results, but not as nice as when I use the IB Large Buffer. I got good coverage with this brush and it's very soft. Overall, it is a good powder brush and I like that the entire set is so petite and portable.
The blush brush I find to be a little too dense (since it is dome-shaped and because it is smaller and the brush handle is significantly thinner, the brush hairs are VERY densely packed). I prefer blush brushes to be a little less dense so that its easier to build up intensity. This brush works fine, but just be careful not to pick up too much powder at once, unless you're going for a super concentrated application.
The eyeshadow brush isn't the greatest. It's really soft and picks up powder nicely, but isn't dense enough. Good for a light wash of colour to the lids and not much else.
The mini round crease brush is a much better version of their full-size IB round crease brush. It is denser and much more resistant than the full-size brush. So soft and applies eyeshadow like a dream.
The liner brush is EXCELLENT with fluidline! I would say it is on par with the MAC 266.
The lip brush is good enough for me, although I generally don't wear pigmented lip products.
And the spoolie is nice for separating lashes after applying mascara. It works fine as a brow groomer as well.
I'll keep updating as I put the other brushes I've bought to the test
