Pentel EnerGel RTX Retractable Liquid Gel Pen 0.5mm Fine Line Needle Tip Black Ink (15)

This is, by far, the best pen on the market today. This is not hyperbole. I write a lot and I go through so many pens, so I am picky. I have not found a pen that writes smoother, puts down a cleaner line with NO BLOBS, is lightweight and durable, with a comfortable balance and grip. The 0.7 is good, 0.5 is excellent (but that's a taste thing). If you care about what you write and what you write with, BUY THIS PEN!

My favorite pens! I love them in all colors and use them every day at work. The write nice, do not smear and they are a nice diameter and weight for people who do a lot of writing.

My new favorite pen! I’ve always used this brand but never this size tip. Very good but idk if I am just writing a lot or if they go pretty quick lol but nevertheless still great quality!!! I have a higher standard for pens now

Best pens out there. Ink is silky smooth, dries fast and is the most lefty-friendly I’ve ever used. Tip is super fine but still flows crisp and legible lines without feeling scratchy or catchy

These pens are great, i use them for work and they write extremely clearly. The .5mm pen tip is great for small and legible printing, notes, etc. I find the .5mm needle tip has a much lower incidence of ink smudging.
