Wow 1 mm and 1.5 are tiny, I ordered some 1.5 mm ones back when that uber long Furling thread was started. They were too small for even a 6/0 thread furled leader. I couldn't use them because I couldn't thread them onto my 6/0 uni thread leaders. I cannot remember where I ordered them from. The brand is Roman Moser , I just checked Google and they are German made. I did order them from somewhere in the states. The info is on that long long furling thread but I cannot locate it on faol. I thought it was JS Stockard but I checked and they only have the 2mm and up.
