Review on 🖋️ Koh-I-Noor Rapidograph Stainless Steel Replacement Point, 0.60mm, Single Unit (72D.2) by Linda Diaz

I have used x-ray pens with different color rings and caps (for different color codes and inks) for many years (1991). I love these pens, this size clogs less and has a very fine line (to fit in small areas, with light ink colors). Pen tips wear out over time and need to be replaced. but they will last for years if you clean them regularly! They require some maintenance (regular cleaning before refilling ink), but it's worth it! I bought an ultrasonic cleaner a few years ago to clean them faster and bought the right pen cleaner to clean them well. They are archival (ink) and will last 100 years or more!
