I have mentioned this seller in another thread. Westwood have confirmed they are "very good fakes" but fakes all the same. There are slight differences in the jewellery when you compare it to the real thing...other items sold by him such as the t-shirts are very obvious fakes (wrong back neck labels, printed sections of design where there should be embroidery etc.)
The cufflinks will only cost $30 or so more from an actual Westwood dealer (if you have one nearby) so I would save your cash and guarantee you are buying the real thing...after all...pieces from Westwood never depreciate in value, it only increases the longer you have it, but if you have a fake it will never be worth anything if you try to pass it on in the future. .
I think a lot of people are fooled by this seller

and I think by starting his auctions high it gives people a false sense of security.
I have bought from Westwood's online retailer -
www.hervia.com and ifyou sign up for emails you are notified ofs ales and special promos. Plus everything always comes in packaging and carrier bags,so it's ideal for a gift.
