POREX Nibs give you design flexibility. Parts can be molded in hatchet, wedge, bullet, and pointed shapes. Vent groves can be incorporated into the nib itself. Arrowhead or stepped designs can be used to avoid push-back problems. While porous plastic parts have inherently wider dimensional tolerances than solid plastic, their resiliency will allow for a compression fit. POREX Nibs offer modern designs, smooth, quiet writing and good lay down.
