PILOTPilot Hi-Tech C Coleto 0.4 mm Gel Ink, Ballpoint Refill, 10 Color Set (LHKRF-1SC4-10C)

Love these pens. The extra fine point allow me to write comfortably in my small and bear handwriting. Not to mention I can have various colors using one pen. I could not pass up on such a good deal.

The gel ink cartridges offer an affordable ink solution without compromising on quality. The smooth writing experience these cartridges provide is truly remarkable. The ink flows effortlessly, creating clean and precise lines on paper. Additionally, the quick drying time ensures smudge-free results, which is particularly handy for those who write fast or have to jot down notes on the go. However, it's important to note that these cartridges are exclusively compatible with certain pens, so owning the pen itself is a prerequisite. Despite this limitation, the gel ink cartridges stand as a cost-effective and high-performing option for those seeking reliable and pleasant writing experiences. I love this ink and I am so grateful that I can finally get it in the good old USA. I used to have to get them from Japan.

I was concerned about the comments that it rips paper. Unfounded! You do have to have a gentler touch. The flow is smooth but not copious so you might feel inclined to press harder. Better for you to get the thicker nib like .5The ink is very thin but no skipping. You might have to adjust your pressure when you switch from regular pens to this one. The refills are perfect for Kikki K Planners. No more scrambling for different pens, you just click and you're good to go. The colors I have in my pen are pink, light blue, purple and orange. I love this and am very motivated to use this in my planner - it makes me happy. Again, the flow of the ink is very thin but not light. Very great colors.

Pros (+) and Cons (-):(+) They're 0.3mm. That alone makes these a steal at $15.(+) They come in an assortment of READABLE colors! (I can't emphasize "readable" enough!)(+) They're gel ink. This means they flow nicely and water damage takes longer to wipe away your writing (ok, in terms of waterfast-ness, water-based < gel < oil < permanent, but who writes with permanent!? They're the smelliest, bleediest things pens out there.)(-) Not so much the fault of the refills, but the 5-slot pen they go in isn't a 100% tight/locking (not as much as the Pilot G-2 pens), so you'll feel an ever so slight "brush" effect on certain strokes. Like, there's a slight "give" depending on how you write, but this is very, very slight. Some people won't even notice this.(-) The pen these refills go in is 100% plastic, and isn't exactly weighted like high end ones. This won't be a problem to most users.(-) The instructions are all in Japanese (but a quick youtube and you'll be on your way. It just caught me off guard that's all.)Honestly, I'm only docking points for the lack of English instructions and that slight "give", other than that, these are hands down the "finest" pen refills you'll find (for a multipen). Har har.

I love pens. LOVE them. I've gone through many brands and sizes, but I must say I love these the most. I have used the Pilot G2 0.38mm refills with the Pilot G2 Pro Retractable Gel Ink Roller Ball Pen for a very long time, but wanted a multi-color pen for my day planner (I have a lot of things coming up and want to color code times so they stand out). I've used the KLOUD City 0.4mm colored pens before and they were just okay (nice colors, but they didn't write very smoothly), so I decided to give these a try after reading reviews. I decided on the 0.3mm pen tip since I like having the ability to write smaller (like packing a lot of words into a single square in a monthly day planner) and I'm super happy I gave it a chance!! These don't drag or skip (they write soooooo smooth) and the colors are brilliant. They write somewhat like writing with a 0.5 pencil lead, except colorful and permanent. I also bought the Pilot Hi-Tec-C Coleto 5 Color Multi Pen Body Component (set of 3), so I am able to organize all of the colors the way I want them between two pens.

Fits perfectly in the Pilot Coleto.

Love the Coleto line. It's one of the better hyperfine pens that produce brilliant color that you can read. The colors are simply beautiful.The best part of these refills is including the click tab in the refill itself. It means that if you put a purple refill in your pen, it has a purple tab. That doesn't always happen with other multipens, which will have refills like purple or turquoise available, but will make you stick them in the standard red blue green black tabs.I use the 3.0 nibs, but I've never had them rip paper. Heck, I have .25 Pilot stick pens, and I've never had those rip papers, either. Maybe the people with ripped paper need to reconsider their grip, and try not to write so dang hard. I write hard enough that you can feel my script on the back of even thick paper like Rhodia, but I've never had a Pilot pen rip a page.

This is a great pack to order with any Pilot Coleto model (these work with all of them) and I've loved the quality of the writing and there is no gappy issue with the ink or clotting, very smooth writing and the nibs are great. I had to order more of the black color since I use that the most, but I can see the other colors lasting me a while. I've ordered two Coleto bodies so that I can carry around 8 colors of the same great pen in a super compact way! Love love love. I really wish there was a 10-pack like this of just the .4mm black refills. I would snatch something like that up really quickly.
