Hi-Tec-C 025 Gel Ink Pen, Hyper Fine Point 0.25mm, Red Ink, LH-20C25, Value Set of 5

Simply the best. The sturdy metal tip produces a solid, thin, clear red line. You won't find anything better, especially at this price.

my favorite pens I use these for everything, the nib is very thin and writes very well. for a 0.25mm pen tip these pens write very smoothly and without any issues. the ink flow is great and a great value for the amount of pens you get the size it excellent, comfortable to write with.

The tip size is perfect. Unfortunately the ink is not very bright at all. Not worth the trouble of sending back.

Précision tip. They have a tendency to clog at some point if I don’t use them enough. But I like them enough to not care about that problem.

So I was a little nervous to buy these pens after I read some reviews saying they were scratchy to write with and the ink wasn’t always smooth coming out (skipping when writing). I bought them anyways because I needed a fine red pen asap for something I’m working on and at first I’d say that the reviews were true. I kept using it and after maybe 20-30 minutes of continued use the issues went away. Yes it sucked at first but now I love these pens and they’re perfect for the fine detail I need. Also, the tip is fine enough for me to write in between lines of a book and it’s still legible.

Perform as described. I use this pen to do electrical wiring diagram. I just wish the multi color set will be available.

They work great.

Color was not bold enough...light red, pink or rose colored.

It has SUCH a fine point but still somehow writes smoothly and legibly! Blows my mind. This series of pens is the best I've ever come across.

I used these in my engineering studies to redline sketches and make general notes ... Superior product ... Made in Japan and they're masterful at precision machining, world leaders ... For those of you that have dried up pens upon receipt ... I've followed up with warranty requests before and have had no problem, Amazon makes it easy ... Like I said, these are precision pens and are top of the line!

Famous pen

Great brand and product. Hard to find something that’s fine enough for my tiny writing tasks. Happy with my purchase.
