rOtring 600 Ballpoint Pen, Medium Point, Black Ink, Black Barrel, Refillable - Smooth Writing, Non-Slip Grip

The rOtring 600 Ballpoint Pen is a high-quality pen that is known for its compatibility with a range of refills. It takes Parker-style "G2" refills, as well as the Fisher PR4 with the supplied adapter. Customers have reported success with Schmidt 900 for a smooth ballpoint, as well as Itoya gel ink refills, and various gel and hybrid refills from Monteverde. The Schmidt EasyFlow 9000 hybrid ink refill is highly recommended for its smoothness and is Considered by some to be the best black ink option. Customers have reported some issues with pen rattling and play in the ink cartridge tip, which may be due to variations in the loosely-sized Parker G2 cartridge. Some users have found the clicker to stop working or even fall off, though others have reported no issues even after years of use. Overall, users have enjoyed the weight and satisfying click of this pen, but opinions on actual writing quality vary. Some have found the internals to feel cheap or poorly made, while others have compared it favorably to pens from other high-end brands. The price point is a common complaint, as users feel it is overpriced given the issues with durability and packaging. However, many have still found it to be a dependable and unique pen that is worth the investment.
