i have purchased from this site a few times. I have received real items and also counterfeits.
I was promptly refunded when I notified them of the counterfeit products i'd received, and the items were also pulled off the site immediately.
i'm quite iffy about the pigments on there only because they are the colours most often seen as counterfeit on ebay.
proceed with caution - but you might be able to bag a bargain!
