here's the reply I got:
[FONT=arial,sans-serif]I'm so sorry to let you know that these items were not on Mac website, these items were just put up my most Mac make-up artist by themselves using mac refills. My advise to you whatever you plan to buy which you are not so sure you better ask the seller like what you are doing because you cannot trust some seller, I'm a buyer too and though I have a supplier and always ask her if I'm not so sure of what she send me[/FONT]
no idea what to think whether she's aware or not, I only asked could she point me towards a link with swatches or where they are on mac's site, those looked suspicious in the first place anyway but there are always people who don't care and will buy....
