i haven't but have my order in for a few things from there. A friend went to a party and said the stuff was fab!! She is the one who put me onto them.
When I went to live in the UK - I got a charm bracelet with aussie charms on - kanga, aussie map, boomerang. Perhaps you could get her a charm bracelet with some aussie charms as a starter that they can add to over time. I have added a few things to mine and want to get three keepsake hearts from my giddy aunt with the dd's initials on.
My ds1 was given a lovely little sterling silver tooth fairy box. We just used it for his first tooth a few weeks ago [awwww]. Unfortunately it's either not British or antique, because it's the wrong size for a £1 coin! But, still, it's very lovely and he was very excited to use it.
