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]

Writes very well, hasn’t skipped been using it about 2 weeks will update if it runs out to quick but its tiny and gel so if it lasts longer than 2 months ill be a happy camper. I replace usually about every 3 months with regular refills cause i write so much at work

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.

D1 size. 167mm long. Has a blue ring so you know what color this is (helpful when loaded in a multi-color pen). I was looking for a D1 gel insert to put in my Big Idea Design Ti Mini Pocket pen. It is a smooth refill. I don't usually write with 0.5mm, I prefer a 1.0mm, but will compromise with a 0.7mm. I will edit once I see how long this refill lasts. For now, I have attached some pics with a sample page (supposedly H517x9 cm). Mine arrived loose, in a bag. I don't mind that. I have it next to a Monteverde ballpoint D1 in brown. Take care, I have read that there is a difference between Japanese D1 sizing and European sizing. My Monteverde and Zebra JSB refill fit the same in my pen. I will keep a ballpoint or another refill as backup if I am soloing this pen.

These are perfect refills for my Zebra Telescoping pen which I keep in my car. I love that the ink is like gel or roller ball - it flows well. I would buy again!

Steel ink cartridge does not fit in G-750 pen, not even close. Returning.... Rufus was incorrect.

I wanted gel ink in my pens and these fit perfectly. They write so smooth!

Just when you thought you knew everything about everything, you find a product that is life-changing. This is NOT one of those products. but it is everything it is advertised to be, so you should be safe acquiring it.

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.

Working good ~~ buy them

Just what I needed for my smart per I

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