I have ivory ferrules and need to replace the tips. I've looked online and searched this forum but I cannot find a source for the fibre pads that are used between the tip and ferrule.
There's Atlas as has been noted but they have a 50.00 min. plus a handling charge. There also is Hightower and Prather but the easiest, quickest and cheapest would be to just go to an auto parts store and get a small piece of gasket material.
