Set of four metal ballpoint pens. Metal ballpoint pens are a popular type of writing instrument known for their durability and sleek design. Ours are made from a metal barrel made of stainless steel and brass metals, which gives them a sturdy and premium feel. The ballpoint pen mechanism involves a small ball at the pen's tip that rotates as you write, picking up ink from a reservoir and depositing it onto the paper. This design allows for smooth and consistent ink flow, making ballpoint pens suitable for everyday writing tasks. Pencils measure 5.5 in.
