uni JETSTREAM PRIME Twist Mechanism Accessory Pack 0.5mm

For a pen, I would get the Smootherpro Titanium Bolt Action Pen, at USD26 for my Miami address: https://www.amazon.com/dp/B098NFPQTG This one is compatible with the Parker G2 ISO style refills, which are ubiquitous I would say, made by several brands, available in a variety of tip sizes and ink types. My Top Recommendation: Uni-ball Jetstream SXR-600 If you are looking for the best possible writing experience in this format, the uni-ball SXR-600 is the standout choice. It uses Jetstream’s famous Hybrid Ink, which combines the fast-drying, smudge-proof nature of a ballpoint with the smoothness and vibrant pigment of a gel pen. Refill Model Tip Size Best Use Case SXR-600-38 0.38mm Precise technical notes or small handwriting. SXR-600-05 0.5mm The "Sweet Spot"—incredibly smooth but still fine. SXR-600-07 0.7mm Maximum smoothness; feels like the pen is gliding.
