howdy, I'm selling these in batches. You get 5 pair of each of the three important sizes: 8.5mm, 9mm, 9.5mm. I can't remember which size corresponds to italian, french, and british, but I believe Sheldon has written something about cotter pins on his site. These cotterpins are made in Taiwan. They each have a washer and dryer, I mean a washer and nut. Price is $18 SHIPPED within the US. Double the quantity for $30 shipped. Mario Girasa, Cambridge, MA
