MONAMINEW FX ZETA, Retractable Ballpoint Pen, Medium Point (1.0mm), Comfortable Grip, Ultra Smooth F5 Ink, Red, 12-Count

I really like the smooth writing feel and the fact that there's no residue left behind. It would be great if they came out with a gel-type pen.

I was first introduced to, and gifted this pen brand on a trip to S Korea.My husband ran out of his Zebra brand so it was an opportunity to get him this model. Korean products are 99.9% high quality, and this one item is definitely better than Zebra and a surprising bargain for it!

Great value for money. Fantastic grip, smooth writing, vivid blue ink. Perfect for daily office work

The pens are more of a fine point than a medium. Write smoothly enough, but most appear pale due to the fine point. Pens arrived quickly from Korea. These will work nicely for the word puzzles I do. .5mm to me is a medium, the company saying extra fine is true in this case!

I literally cannot write with these. I’m Korean and I really wanted to like this. But I just cannot use this as writing instruments. The ink does not come out consistently and I always have to redraw what I wanted to write like five times. I have never use these pens for more than 20 seconds at a time because that’s all I give it to work lol. Of course, these pants do not work, and I have to use another set of pens. It’s so unfortunate that I had to waste my money on these.

This is probably the best pen I have found on Amazon.

Very well made products.

I am obsessed with fine/extra-fine/micro pens so finding these was too exciting. I love all of the colors - I am a sucker for sets that include less traditional colors like brown and blue-black.As you can see most of these pens are awesome. They are fine. They are smooth and not scratchy and they write well. However, there are a few that do not perform as expected. I’ll exchange them, as I’m still hopeful.
