As far as I know, at present we don't have a
Menzerna supplier in the UK (well not a reliable one). I believe one may exist, but are very unfriendly and the name of the company escapes me.
For ordering and sending to the UK, i'd try the following site

These guys are based in Portugal and you should be able to get PO85RD sent to your office free of any duty as it will be inside the european union. I do believe they will send to the United States as well, but you will be liable for import duty.
We know Klasse in europe (well my knowledge extends to the UK), as Klasse.
For reliable UK suppliers i'd have a look at... (I hope I am not breaking any rules by posting these links!)

I guess it depends what products you are looking for, I would imagine you should be able to find most of what those sites sell in the United States. I am a big fan of Ranney at Pakshak and when I can't buy what I want in the UK, usually tend to order from the US.
