I have shipped everything except a full bike and frame to Japan. Japanese collectors love the old French stuff and select Italian and English bits, they pay top dollar for the right part. I love our Japanese friends when I am selling, I hate them when I am bidding. That's why selling worldwide is the only way go on ebay.
USPS is by far the most economical way to ship, nothing else comes close and I have never had an issue with damage although I pack very well.
