Not typically a big fan of Sarasas, but I have to say this pen does its job. The ink dries almost instantly after touching the paper, and highlighting over what you just wrote feels like highlighting over printed text in a book. No smudges at all.
Of course if your paper is exceptionally glossy, it might not dry as quickly, but this pen performs exceptionally well on normal paper. Perfect for taking notes in class.

My first round with these pens was underwhelming, but I think I just got a fluke because I reordered and I am THRILLED. These are my everyday pens now. My original . 5 in black is nearly out of ink and I have purchased a refill already. These are fantastic pens and I reccomend highly. They do not smear, and I've paired them with Crayola markers, tombow dual brush pens, and the Mildliners. After three seconds they do not budge.

The ink is smooth and though it's not the blackest, or the bluest, it's still very pigmented.

Bleed through is not a problem, though on really thin paper youay get some ghosting. My kokuyo campus paper LOVES these pens. They even work well on cheap dollar store notebook paper.

I will be purchasing many, many more times.

This is my FAVORITE pen of all time for note taking. I find that on certain paper (typically low quality printer paper or standard American notebook paper) the gel ink will smear when highlighted. However, this ink does not smear with highlighter on Kokuyo campus notebook paper and is incredibly smooth to write with. I enjoy the push clip mechanism and the rubber grip is comfortable in my hands. I love to use this pen with the staedtler textsurfer highlighter. I have not tried the other colors but I am looking forward to. 5/5 would recommend this product to anyone.

Easily one of my favorite pens right now. The ink flow is thick and puts a lot of other pens to shame. It holds up to highlighter like it says it does. I also think it looks cool. Definitely my go-to pen during Quarantine 2020.

The pen looks cool, writes really smooth for the price, for the price the quality of the pen is amazing and it feels great in the hand
