Pilot Hi-Tec-C Coleto Gel Ink Pen Refill 0.4mm, Blue, × 6 Packs/total 6 pcs (Japan Import) [Komainu-Dou Original Package]

good

These are my go-to pens! I love the fine print and how precise they are. The only downside is how quickly the ink runs out for me. To be fair, I use them everyday and write a fair amount. I use to just buy the variety 10 pack for all the colors, which I love. But this time I also bought this pack of blue since I use that color most, and that has worked out well for me. Love these pens. Never going back.

been using this ink for one year and it is very nice. i like the customizable pens.

I love that I can pick and choose the colors that I want to load in my multi-color pens. The only downside is that they run out of ink quickly.

Good quality, nice price,,
