Felttip

A felttip, commonly referred to as a felt‑tip pen or felt‑tip marker, is a writing instrument in which ink is delivered to the page through a porous tip made of felt or a similar fiber. The felt nib absorbs ink from a reservoir and releases it onto the surface by capillary action, allowing smooth, continuous lines that can vary in width depending on the tip shape and angle of use.

Construction and operation: The ink reservoir can be a disposable cartridge, a built‑in chamber, or a refillable system. The tip, often available in broad, chisel, or fine bullet shapes, controls line width and durability. Fluids used in felttips vary: water‑based inks are common for school and art markers and are typically washable; alcohol‑ or solvent‑based inks offer faster drying and greater permanence; oil‑based or pigment inks provide enhanced lightfastness and fabric compatibility. Some felttips are designed for temporary use on whiteboards or other nonporous surfaces, while others are intended for permanent labeling on paper, cardboard, plastic, or textiles.

Uses and varieties: Felttip markers are widely used in education, graphic design, illustration, crafts, and labeling. They are available in a range of colors and intensities, with permanent and erasable variants. Different products emphasize features such as quick drying, odor, washability, or resistance to water and fading.

History and impact: The modern felttip marker emerged in the mid‑20th century and quickly became a staple tool in offices, schools, and studios due to its ease of use, bold color, and versatile nibs.

Care and maintenance: When not in use, cap the marker to prevent drying. Replace worn tips promptly, and avoid pressing the tip against hard surfaces to reduce fraying. Proper storage and handling extend marker life.
