Optimized ink flow management for coloring markers
As a global leader in the Science of Ink Flow Management, Porex has a broad portfolio of products to optimize your coloring marker’s performance. POREX coloring marker nibs are designed with the perfect porosity and capillarity for the smoothest user experience . When paired with our reservoirs using the optimal fiber type, density and wrap for your marker, this combination creates the ultimate ink flow management engine for your specific coloring marker design.
Benefits of POREX coloring marker ink flow management solutions include:
- Maximum ink flow delivery and utilization.
- Highest degree of leak protection with the optimal matching of nib and reservoir technology.

Reservoirs for Coloring Markers
Maximum ink utilization combined with leak protection

Nibs for Coloring Markers

Reservoirs for Coloring Markers
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 coloring markers.
Our reservoir media designed specifically for coloring markers:
- 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 coloring marker’s requirements.

Nibs for Coloring Markers
Customize ink flow management with two nib technologies
Porex offers two distinct nib technologies for use in coloring markers depending on the specific design needs of the marker:
- POREX® sintered particle nibs are 3D-molded porous plastic nibs with the ideal mix of porosity and capillarity to deliver ink to the writing surface. Safe for children’s applications, our sintered PE nibs write with a smooth, durable feel.
- POREX® polyester fiber nibs are a combination of polyester fiber and bonding resin, optimized for high ink flow and shaped to your coloring marker’s specifications.
Manufactured into nearly any imaginable shape, both types of nibs for coloring markers deliver high ink flow to work in tandem with reservoirs to deliver a consistently high amount of ink.
