This is a hotel business advertising ballpoint pen. The pen body is made of aluminum and rubber plastic with high strength and toughness. The pen body is designed with a concave and convex design to prevent slipping and ensure easy writing. The logo can be customized. The core can be ejected with one click, which is convenient and quick. The core can be retracted when not in use to protect the pen tip. The flexible pen clip is not easy to break and can be clipped on paper documents for stable and portable use, saying goodbye to the trouble of losing it. At the same time, it is not easy to roll off when placed on the desktop. The ink is evenly discharged, not easy to leak or clog, and the 1.0mm pen tip design provides a smooth and diverse writing experience.
