Understand about the shipping cost saving Tony, but perhaps in future just one blade at a time. Maybe too much for them to get their heads around it.
Only takes one narrow minded individual down at customs to put a spanner in the works. Whilst some, like us guys enjoy old antique arms, there are those that find it unacceptable or strange in this "modern" age and may get a kick out being a pain and feeling all important. Either that or just inadequate with work skills, which dont surprise me as lately with cost cutting in all lines of work, seems to be the norm.
Only yesterday got a tiny reminder, this hobby aint for everyone,
Good luck with your swords.
