Zebra JF-0.5 Gel Ink Pen Refill, 0.5 mm, Black, 5 Refills per Pack (Japan Import) [Komainu-Dou Original Package]

Excellent refills for the Zebra Sarasa Clip pens. Great value as you get multiple in a pack, exactly the same ink that comes in the original pen. Smudge resistant and really smooth and comfortable to write with. Would highly recommend!

Refills arrived safely, they write great. I've had no issues with the ones I have used so far, the ink quality is the same as what originally came with the pen.

is this a universal refill?? wow it works as a refill on MUJI pens and Sharpie S GEL clicker pens!!!! awesome. smooth writing, no smudge, use it for work mainly coz I use 0.38 or 0.3 on others. not bad.

Pens were delivered as expected with a handwritten note. Not necessary but above and beyond service considering the price. The refills work wonderfully.
