The BIC 4-Color Retractable Ballpoint Pen is a versatile writing instrument that packs four ink colors — black, blue, red, and green — into a single, convenient pen. Sold at Costco in a 15-count multipack, these pens offer excellent value for classrooms, offices, and home organization projects.

Each pen features a retractable design with a side-click mechanism that lets you switch between colors effortlessly. The 1.0mm medium point delivers clear, dark lines for everyday writing tasks including note-taking, journaling, list-making, and color-coding. The wide barrel design provides a comfortable grip, while a built-in lanyard hole and pocket clip keep the pen within easy reach — clip it to a notebook or wear it around your neck.

BIC's fast-drying, water-based ink is smudge-resistant for clean, neat results. These pens are refillable, extending their useful life and helping reduce single-use plastic waste. Model number WC4CT072.
