Ah... so if you're in the UK, you can't buy from the .com site? Or can't see results that ship to your country? If this is so, I've learned something else. That in addition to hiraethus being British (can I see a Welsh flag by your name when I expand the page?); that some Swisscard files are made of glass; and that replacement glass files may not be readily available (a poor show by the Vic distributors).
I hope you find a glass file soon, hiraethus.
