POREX® Nibs are designed for a broad array of writing instrument applications such as highlighters and children’s coloring markers. Molded nibs provide a smooth writing feel and the strength and shape required, either with or without a vent groove. Vented nibs allow for ease of assembly, while ensuring the functionality of the capillary system without ink leakage.
Engineered to meet customer performance specifications, POREX® Nibs are available in a wide selection of standard wedge, bullet, and conical designs. They can also be custom designed to meet customers' specific needs, as well as with special material formulations to optimize capillary systems.
