What is a felt tip pen?

A felt tip pen, also known as a marker pen or a porous point pen, has a pointed tip made of felt or porous fiber material that contains colored ink or dye. The ink or dye flows through the fibers and onto the surface being written on, creating a precise and vivid impression. Felt tip pens come in various colors and thicknesses and are used for a variety of purposes, including drawing, coloring, writing, and highlighting. They are often used on smooth surfaces like paper, cardboard, plastic, or metal and are popular among artists, designers, and students due to their convenience and versatility. However, they tend to dry up quickly if left uncapped and can bleed through thin paper. Some modern felt tip pens are refillable and made of eco-friendly materials, making them a sustainable alternative to traditional disposable pens.
