Zebra 0.5mm Royal Blue Gel Ink Refill (RJSB5- RBL), for Zebra Multi Function Pen Shabo X Ballpoint Pen, × 5 Pack/total 5 pcs (Japan Import) [Komainu-Dou Original Package]

The .5mm is fine point; but it writes very smoothly, as you'd expect from jell ink. The ink color is a very dark blue. Fits both my Rotring and Troika multifunction pens perfectly.

Working good ~~ buy them

Çok ince ve mürekkebi atlamadan yazıyor. Çok başarılı buldum. DİKKAT imza atmak için tercih etmezdim!

This is just what I needed, I was looking for smooth and fine Gel-ink refills for my Moleskine smart pen and these refills are perfect.

THE best-writing 0.5 mm ball pen ever. Very smooth, steady ink flow at most writing velocities. Can even write variable-thinkness lines if you are careful. But it does run out fast. But I get what I paid for, so I'm happy.
