A pen holder is a small container designed to keep pens, pencils, and other writing instruments organized and easily accessible. It can be made from various materials, such as plastic, wood, or metal, and comes in different shapes and sizes. Pen holders are commonly found on desks, in classrooms, and in offices, helping to reduce clutter and improve productivity. Many pen holders also serve decorative purposes, featuring unique designs or colors that enhance the aesthetic of a workspace. Some may include additional compartments for storing other stationery items, such as highlighters, markers, or erasers, making them versatile tools for both students and professionals.
