Pilot Hi-Tec-C Coleto Gel Ink Pen Refill 0.3mm, 15-color Set(Japan Import) [Komainu-Dou Original Package]

Colors are very vibrant. I use them as an RN who needs multi-colored pens for note taking. They don't seem to hold a lot of ink so I have re-ordered a few times, but the ink is thin, doesn't run or smear easily, and writes more smoothly than many competitors.

I love the Coleto pens and the gel ink. I have 3,4,5mm inks. The 3 gets a bit scratchy and you have to press harder, but you get a thinner line and it doesn’t look thick when you write small. So these are great for me. All the colors are great. If you use a color then decide not to use it, just put some chapstick or beeswax on the tip and put it in a ziplock bag so it doesn’t dry out as quickly. Once the wax bead is removed, I think you have about 1 year before it totally dries out.

Love the color assortment! These refills are good for fine details when color matters the most. The lines are so precise I sometimes find myself using these to outline the letters/marks made using a different pen/marker.

I was looking for these beacuse I had a pen body for them and they are cheap compared to other places !! Plus they write so smooth!!

These are an refill for pens i have and no problem at all

great for the colecto pen!

I purchased a 15 color set and only received 10 colors. Having issues getting what I paid for

Since the point is so fine, it skips quite often and you can clearly hear the pen scratchy the paper. So writing it isn't as smooth. It's great if you have to make a cheat sheet with super fine handwriting. I use it to squish as much information as possible on my flashcards.Also, the ink gets used up really fast, so you might end up having to buy the 5 pack of black ink.
