Description Are you a pilot, police officer, jet-setter, or live in a high altitude area that's fairly dry? You might want to try our New Grafton Ballpoint Refills 1.0mm instead. Unlike our Grafton Metal Gels that are filled with water-based ink, the new Grafton Ballpoint Refills are an oil-based ink that are less likely to freeze up when your cruising at 35,000 feet, crop dusting, or handing out tickets. Specs Three ballpoint ink refills 1.0mm Includes spacer and spring for use with Grafton Pen Copper tube Stainless Steel Tip Compatible With Full Size Grafton, Mini Twist, and Brass Mini Twist Not Compatible With Mini Click Pen
