Pilot Hi-Tec-C Coleto Gel Ink Pen Refill 0.5mm, Black, × 6 Packs/total 6 pcs (Japan Import) [Komainu-Dou Original Package]

Item as described

I'm looking at the (more expensive) two color pens, as the 4 color ones have the bigger barrel, and no rubber grip. So I added one on, making it harder to pull out of the Pocket Protector, plus the cap may come off, so I dont take it outside of the house. But I think Pilot has the best gel ink and cartridge with this hi-tec roller. I prefer a darker blue than this slate blue, but they offer it. I think.
