(You can get them on eBay)... but I'd ask for a Scottish thistle harness brass. It's a small unbreakable item that won't take up too much room in the luggage.
Another small unbreakable that I like- is a souvenir printed tea towel. I know they are old fashioned- that's what I like about them. USA tourist attraction/towns never make tea towels of their sites- but in Europe they do, so to me it documents a little culture difference to cherish.
A BIG jug of Tullamore Dew.
An Irish fisherman's sweater (the ones with the oiled yarn - they smell funny and cost a bunch, but repel light rain and are the real McCoy)
Belleek china - but only if it's still made the way it used to be.
I'm so jealous. I spent three months in Ireland riding at Burton Hall (home of Fru & Foster, and where Snowbound spent some time before he & Bill won Gold in Mexico City). No place like it in the world. Only I fear (from some TV shows I've seen) it's changed as much as the rest of the world.
Oh - and tell him not to buy any tourist-trap tchatchkis that have Gaelic on the bottom. Probably says "Made in China" (in Gaelic).... When I was there, it said Made it Japan.
Here it is St. Patrick's Day - and I'm GREEN WITH ENVY!!!! And with the last name Coronios, a bit envious of his going to Greece, too.
I second Dubarry. I'd also request Cadbury's chocolate (no, its not the same as the stuff you buy in grocery stores here. That's hersheys and it doesn't count!), and polo mints. Extra for the horses because they love them as much as I do.
I used to say WOOF boots but now you can get them pretty much anywhere here.

I have spent some time in both places and....the woolens can not be beaten...we just don't have that quality of wool with lanolin left in here...heavenly. Anything in crystal is beyond the moon there..I have examples from both Ireland and Scotland...Beleek is wonderful as well. What I always get when I have the chance to go to either place is Adult sized Jodphurs...heaven! Only children in N. America are allowed the comfort that our UK sisters take for granted!
