the Pen (Kalem)

A pen, or kalem, is a portable writing instrument that uses ink to produce marks on paper. It typically contains a reservoir of ink and a tip that transfers ink onto a surface when pressed or moved. There are various types, including ballpoint, fountain, and rollerball pens, each with different mechanisms for delivering ink smoothly. Pens are essential tools for writing, drawing, and signing documents, offering precision and ease of use across personal, educational, and professional settings. They are valued for their convenience, durability, and ability to produce clear, permanent marks.
