Where can I get custom pens?

Does any one know a good site where I can get custom pens? I want to get some made up with my details on them for handing out to friends and family – I am moving away soon and it’s a good idea for sharing my new address and phone number etc with my loved ones. It’s more interesting and unique than sending out ‘new address’ cards any way because let’s be honest people always lose those things, I know I do any way. Whenever I get one I plan to put it somewhere safe, but then when the time comes that I actually need to find the persons new address or phone number I have no clue what I have done with it, if it was on a pen though I’d be much more likely to know where it was at any given time.

I think it’s a great idea any way
