There is an entire thread about this in the "ask and anwered makeup questions" section, but here is what I wrote..
I'm so happy to see this thread, I was actually going to start one..
So, here's my story.
First, I've never returned anything to MAC. I've, for the most part loved every purchase I've made..
Until yesterday.
I purchased three "adoring carmine" basic brush sets (50.00 each!), I was planning on giving two as gifts and keeping one for myself for traveling.
I tried them last night (we went to Knots Scary Farm!) and the brushes were C.R.A.P....
I went to MAC today and spoke to a fab gal in Mission Valley, she explained that they are not the same brushes. That the holidays sets (as explained above) are machine made and cut and the hairs are synthetic.
Boooo...(lol, no pun intended!)
I was short on time and didnt have my "wish-list" so I'll be returning them tomorrow.
I heart MAC, and make-up is my passion, but I highly reccommend that you save your money for the full size ones. I'll just keeping using my CVS brushes (those are fan-freaking-tastic) and were under 10.00!!
