Length

Once you have measured the length of your refill, find that length in the list below. The same refill might vary in length by as much as 2mm due to manufacturing tolerances and other factors. If you don’t find a category below that matches your measurement, browse the categories corresponding to the next measurement up or down. For example, standard ceramic rollerball refills are officially 111.1mm, but actual measurements can vary from 110mm to 112mm.
