A pen holder is a small container designed to keep pens, pencils, and other writing instruments organized and easily accessible. They come in various shapes, sizes, and materials, such as plastic, metal, or wood. Some pen holders are simple cups, while others may have compartments for different types of stationery. In addition to holding writing tools, pen holders can also serve as decorative items for desks or workspaces. Many people choose pen holders that match their personal style or the theme of their office. They can be found in stores or online, often alongside other office supplies like notebooks and sticky notes.
