Definition of, ‘Fine Writing’ 

The German-made spring-loaded Fiber Tip on this refill allows for the finest written line to be maintained even with continued use. This ‘shock absorber’ effect is achieved by the small internal spring directly behind the tip which prevents the porous fiber tip from widening or spreading. The result is a fine line with added comfort and superior contact with the paper, enhancing your writing or drawing experience. 

This Fiber Tip fits most capped rollerball pens which require an international standard-sized refill. Your choice of back or blue ink.
