Ok i buy my paper from this site although the company in question hasn't a damn clue about keeping there stuff to just 1 site they range it over 7 different 1's that i came across.http://www.m-techdirect.co.uk/papers.htm
near bottom of the page and the bloody prices have changes since i bought holographic paper .
Give An Instant 3D Effect to your images @ £3.75 pack of 5 A4 Sheets
and this site http://mediadepot.mtechdirect.co.uk/acatal...lic_Papers.html
Just for there phone number i always ring them and get it dealt with over the phone also order monday before 3 pm i usually get tuesday afternoon.
There prices are a little bit more expensive than other sites,but found they are the best quality and there Silver Film Paper is brilliant which i use for all my foil effect covers.
Hope this helps the second link they have loads of other interesting papers for designing and some nice design kits also.
