Write comfortably over an extended period with the HMM Aluminum Ballpoint Pen. Made of aluminum alloy, this device is both lightweight and durable. Weighing just 22 grams, the HMM Ballpoint is comfortable to use. Likewise, it is ideal for writing for over long periods of time. The heavy-duty spring found in the click structure gives a firm and sturdy feel in your hand. In addition, the RAW color reveals the natural beauty of the material. Similarly, vibration polishing is used to age the body, providing subtle texture and better grip. Military-grade hard anodizing is used to process the body of the GUN color, resulting in greater hardness. Furthermore, the anti-corrosion and anti-scratch surface provides a unique writing style that continues to get better with age.
