Hey InaJ!
I got the 10pc set on eBay which is similar to the one on the FB page for about $18 with shipping. I like the brushes.
The medium sized ones are the easiest for me to use. I use it to blend cream/liquid foundation. The bristles are very dense and very soft. The brush doesn’t have as much movement on the face say as a traditions kabuki powder brush. But when used in circular motions, it really even out the complexion and makes the cream blend well with the skin.
The eyeliner brushes are also good for winged liner. But I usually tight line or just smudge my gel liner into the eyeshadow. I can’t find much use for it.
I have tried but I can’t use the biggest one or any of the medium sized ones for powders, highlighters or blush. They do ok with cream highligher but I prefer a round soft tapering brush with some movement.
I definitely recommend getting the cheap version before you take the plunge into something expensive. They are all made in China. So is Artis.
