A marker pen, fineliner, marking pen, felt-tip pen, flow marker, texta, sketch pen or koki, is a pen which has its own ink source and a tip made of porous, pressed fibers such as felt. A permanent marker consists of a container and a core of an absorbent material. This filling serves as a carrier for the ink.
