This review applies to every One P gel pen I purchased last month.

Three stars for (1) adorable pen aesthetic, (2) overall sleek design, (3) unique color.
Minus two stars for the skipping, misbehaving ink (both .38 and .5) and slippery, too-short body that makes writing with these pens a very uncomfortable experience.

For those wondering why I bought more than one, they were intended to hold my Energel refills when traveling, but it turns out those refills do not fit well in these -- the push button is very hard to press down -- so I have filled them instead with Zebra Sarasa Nano inks.

For those who care, the limited edition smoky Nano inks fit far better in these pens and coordinate very well with the body colors: Smoke Ochre in Coffee, Smoke Khaki in Fresh Mint, Smoke Blue in Soda, and Smoke Pink in Yogurt.

Extremely cute chubby pen. Writes smooth on different paper. But I don’t recommend to write too long because it does get hard to hold after a while. It’s not comfortable at all, my hand starts to hurt.

Love the cute, short and stocky body of this pen and the pastel/minty shade. I usually go for a 0.5mm but the 0.38 still looks good.

Feels great in hand!

Color is so cute! The small chubby size is very comfortable to write with. It’s a great pen to have as a student when you have writing fatigue often.

This pen is very comfortable to write with. I have small hands so I did not have an issue with this pen being shorter than other Uni pens. I like that it does not have a rubber grip but the matte finish keeps the pen from being slippery.

Can fit anywhere and still feels like an absolute unit. Awesome to write with and hold in hand

I really wanted to love this pen after reading the reviews, but it's a bit scratchy
You have to really hold it at an angle from the paper for it to not skip.

I love the thickness of this pen. It feels great in the hand. Bought one for all my friends at work.

It’s not a bad pen. Writes better on certain types of paper than others (I find that it doesn’t do well on thicker paper). It has a deep black color and does not smudge as easily other pens.
