UK Screenwriters - Brads? Paper?

So I've been trying my best to search through tons of websites to find all this sort of stuff, and it's getting to an extremely annoying point. Am I plain blind, or is this stuff actually impossible to get a hold of in the UK?

I'm talking, of course, about the industry standard Acco brass fasteners. They seem so easy to get hold of in the US, but over here, impossible. I've read that these are the specific ones to use and that cheap imitations wouldn't go down well... which doesn't fill me with any confidence.

As well as this, how about the US letter paper? I have been able to find a few places to source this, but not as easy/cheap as it would be in the US - and it's not pre-punched with the 3 holes, which would be another headache.

So, any other UK writers that have been through this? What was your solution?

Also, sorry if this has been brought up before. I've searched the forum and found threads about what brads to use etc. but nothing pertaining specifically to the situation of being based in the UK, so forgive me if I've not looked close enough!

Thanks for any help!

Thanks for the responses guys.

I've bought a box of the Acco 2-hole fasteners mentioned and they work great. Of course, for sending to the US they wouldn't suffice - though I'm glad you mentioned Writers Store, clockwork, as they do send internationally... I wasn't aware of this. The shipping is expensive but I suppose one would have to bite the bullet on that when it came down to it!
