German made Monteverde spring loaded fineliner refills fit most of the world's finest rollerball pens. The spring loaded fiber tip on this refill allows the finest written line to be maintained even with continued use. The shock absorber effect achieved by the small internal spring designed directly behind the tip 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. Sold individually
