By toto850MAC released a new brush not so long ago and it's called the 286, basically a duo fiber eye brush. It first came out with the Holiday 2011 collection in a SE brush set with short handles.
For those who don't know: the SE brush sets are mass produced by machines (m.a.w. not hand made!) so the quality is not the same as the full size MAC brushes (read: crap!). But to avoid any confusion, this the review for the full size MAC 286 which is permanent. :)
My first impression about this brush was that it's an exact dupe for the Laura Mercier Finishing Eye brush. But comparing and seeing them side by side they are not quite identical after all, although they look very much alike.
If you look at the pics: on the left is the LM Finishing Eye brush and on the right you'll see the MAC 286.
Both brushes have been washed and what I noticed is that the LM brush keeps its shape better than the MAC one. After washing the MAC 286 poofs out a little making the brush less dense.
The MAC 286 is a bit softer but still good for blending colors in the crease or to soften the hard edges of your e/s application.
