Zebra 0.5mm Blue Ink Refill (JF-0.5), for Zebra Sarasa Clip 0.5 Gel Ballpoint Pen(JJ15-BL), × 5 Pack/total 5 pcs (Japan Import) [Komainu-Dou Original Package]

This pen refill works perfectly with my favorite pen. The ink flows smoothly and consistently, with no skipping or smudging. Writing feels effortless, and the lines are clean and sharp. Installation was easy—just popped it in and it was ready to go. It’s a reliable refill that brings new life to my pen. Highly satisfied!

these zebra clip on pens are one of the juiciest pens i have ever used. the ink flows out generously, and the ink is super pigmented as well. you cannot go wrong with the sarasa clip pens. i like how these pens are refillable.

works well as refill for Zebra pens

My son introduced me to these Sarasa pens. I like that they come in different colors on the outside, as well as different ink colors. Rather than throwing away the pen casing I am happy that I can get refills and continue to use them.

Perfect for my Sarsa Pens.

Just not for the pens I thought double check your fitment in the hard product description near the bottom

The blue is not really blue. It's more purple.

Love these for my zebra sarasa pens! Always purchased the refills and work great! I typically have 0.4 but this 0.5 works just as great. Great ink flow and no leakage
