Reservoirs for Highlighters
Maximum ink utilization combined with leak protection
POREX® reservoirs are formed from a controlled density of fibers in an extruded seal, allowing you to contain and deliver the maximum amount of ink to your highlighters.
Our reservoir media designed specifically for highlighters:
- Maximize ink utilization–Our customized ink flow management solution combines a nib and reservoir to deliver the maximum amount of ink.
- Ensure leak protection–Capillary forces and materials are customized to your specific highlighter’s requirements.

Nibs for Highlighters
Customize ink flow management with two nib technologies
Porex offers two distinct nib technologies for use in highlighters depending on the specific design needs of the marker:
- POREX® sintered PE nibs are 3D-molded porous plastic nibs providing the ultimate in smooth writing feel and highly durable to keep their shape throughout the life of the highlighter.
- POREX® polyester nibs are a combination of polyester fiber and bonding resin, and are compatible with most inks including high solids/highly pigmented ink.
Manufactured into various customizable shapes, both types of nibs for highlighters deliver high ink flow to work in tandem with reservoirs to deliver a consistently positive writing experiences.
