Got a Jinhao 10 or 20 fountain pen that needs a fresh nib? This 2-pack replacement nib section set is exactly what you're looking for! Each one comes with an iridium-tipped stainless steel extra fine nib that writes super smooth and crisp. The best part? It includes a pre-installed 5.5mm diameter ink converter, so you can use your favorite bottled inks. Swapping is a breeze—just pop the old section out and click this one in. No tools needed! Important note: these only work with 5.5mm cartridges (not the standard 2.6mm or 3.4mm Jinhao ones). If you're new to fountain pens, here's a tip: after inserting ink, let the pen sit upright for 15-20 seconds to get the flow going. If the ink gets spotty, just soak the nib section in warm water for a few minutes. Perfect for journaling, sketching, or just everyday writing. Give your pen a new life!
