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 for the best writing experience. 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. As with our gels, we have added more ink and vastly improved the writing experience. Currently, we only have the 1.0mm refill but will soon get more in different sizes. Specs Pack of Three - Ballpoint Ink Refills 1.0mm Includes spacer and spring for use with Grafton Pen Perfectly Weighted Copper Tube Stainless Steel Tip Compatible With Full Size Grafton, Mini Twist, and Brass Mini Twist Not Compatible With Mini Click Pen
