AMAZING
I loved these pens there great if you’re left handed (like me) they write smooth and dry almost immediately love the black ink, no smudging and over all a great piece for the quantity of items.

Great pen, fast drying
I love this pen and use it often for notes and crossword solving. Here are my pros and cons. Pros: - Fast drying - Dark pigment - Relatively less scratching and feedback - Comfortable with heavy-handed writing and small hands - Less bleeding with heavy-handed writing Cons: - It can have the occasional ink pooling when writing after a period of not using the pen - Can smear if you write fast - The clip is not as deep as I initially thought - so it is not a pen suited for fieldwork or putting on pockets or clipping on clothing, clipboards, etc.

TEacher's Best PEN!
I won't be stealing pens from coworkers and kids anymore. I found the greatest gel pen on the market and plan to buy two more boxes for the upcoming school year. These pens are smooth, reliable and do not smear or spread with a highlighter! You won't be disappointed!

Love these pens.
These are the best pens for journaling. It writes smoothly without clumping or skipping. Made with the quality Japan is known for. And I got this pack of 8 pens for a great price.

Not as good as expected
I saw a lot of great reviews about these pens. I was looking for pens that wouldn’t smear with highlighter. I usually use Pilot G2 pens which smear even after waiting to dry. These pens don’t smear at all; they just don’t write as smoothly as I would have expected and they skip quite a bit to be brand new.

It's a great pen. Can use a highlighter without smearing. Easily my favourite pen at this point.

I've had to throw out multiple ones due to ink not dispensing properly. I'm left handed and I don't know if that has anything to do with it. I'm a chef and I keep the pen in my arm pockets in my chef jacket, always upright. When I use it the first time it's fine, but after a few minutes the ink starts skipping and it's very frustrating.
