I was just going to post that PierrePhil at Beaufort ink sells them
Another reason to call Phil at Beaufort . I live in France and I have never had a bent refill from him despite the best efforts of the uk post office and their counterparts in France this is over many yearsRefills arrived today. An apology from Royal Mail, three refills missing and the other two bent. Chucking five loose refills into a C5 envelope with no other packaging seemed a bit optimistic to me. eBay vendor contacted, hopefully some well packed replacements on the way soon?
