This refill is designed for a ballpoint pen with a medium point and black ink. It is part of a collection of writing instruments created to provide comfortable writing experiences. The original pens in this line were introduced in 1995 to address the need for more ergonomic writing tools. Over the years, the collection has expanded to include various colors and styles, from vibrant neon to professional shades, and different point types such as gel, ballpoint, and mechanical pencil leads. The latest addition is a multi-function instrument that combines a pen and pencil, offering five writing options in one device, including different ink colors and mechanical lead. All pens and refills are retractable and refillable, ensuring long-term use. The design emphasizes comfort and ease of use, with studies indicating high comfort ratings for users with and without arthritis.
