Funny Educational Ballpoint Pen

The pen contains two steel balls within its structure. When the pen body is rotated, the steel balls move accordingly. As they travel from one end to the other, they follow multiple pathways, resembling a maze-like pattern. The pen holder is designed to securely hold items together, such as pages or books, and prevents the pen from rolling off the desk or becoming misplaced. The pen features a 1.0mm tip and a lightweight body that is not only durable but also wear-resistant, offering both flexibility and practicality in use. Black ink.
