Love these pens, coworkers are hooked!
I’ve been a fan of these pens for awhile, perfect for those who are writing small. My coworkers have stolen some from me overtime and went on to purchase their own haha. Definitely repurchasing!

I found my true love
After receiving this pen from the box and test it out, I was very impressed with the tip and the comfort, I didn't really notice about the thickness because I usually use gentle flicks to add details. Pen quality is average like the plastic feels strong. I recommend for people who likes to sketch and write (it doesn't smear)

Perfect pens!!
LOVE these pens!! I use them daily - they write so smoothly and the ink is so pigmented. I use them at work, and in my daily journal writing.

Love these pens
These pens are great. I like the fine point. The ink comes out of the pens consistently and I have no issues using them. They are basic with no frills, and that's exactly why I love them. They also write on fabric well. I sew, and I've found that they're great for marking patterns on fabric in places where I know any stray pen marks will be hidden by seams (which is basically everywhere).

Might help you write more neatly!
These pens are good! I’m usually a fan of clicker pens and not the cap ones. With the thickness of 0.38 mm pens it feels like I’m able to write just a little bit neater. Weight is super light. Haven’t had any problems with writing in the journals I’ve been using.

This is the best standard pen I've ever used - buy it and love it!
Wow. This is the first time using this product, and I am incredibly impressed. I've always been a huge pen/pencil junkie and neat-freak. I'd fallen in love with the feel of a kind of Bic Triumph pens, but the discontinuation of BIC Triumph Roller, Extra Fine Point (0.5 mm), Black Ink, Dozen Box (12 Pens) made me search elsewhere. The pens that I'd used as a staple cost around $50, which is too much considering I'm a college student and write nonstop! I found this product and am incredibly impressed. The fine point is gorgeous and accurate, and the gel is always flowing. They are a tad shorter than their American cousins, but they last a long time because of the fine point - one pen wrote about 50 pages of notes in cursive on college-ruled paper... and it's still not empty! If you want a crisp, accurate pen that flows well and lasts a long time, I recommend this product! It's my new staple! I'm also posting two photos - one so you can see just how large and loopy my cursive is, and the other as a comparison to some other pens of the same breed. I will note that I primarily use cursive, and I am kind of embarrassed by my print... You can see the fine point of Signo clearly on the college-ruled paper! The pens in the comparison picture, top to bottom, are the Sharpie Pens, Fine Point, Black, Box of 12 , Sharpie Pen Retractable Fine Point Pen, 3 Black Ink Pens (1753176) , Bulk Buy: Sakura Gelly Roll Fine Point Pen Open Stock Black GR-37321 (12-Pack) , Bic Triumph (linked before), uni-ball Impact Stick Gel Pens, 1 Gold and 1 Silver , and this product! Hope this helps you choose what's best for you! Happy writing!

ottima penna, scrive molto bene, punta fine 0.38 (esiste anche 0.28), non fatela cadere di punta senza il cappuccio rischia di non scrivere più.

This is the best micro-tip pen I've ever found. The ink is very dark, so very legible, regardless of the fineness of the ballpoint. It seems to be fast-drying and difficult to smudge, and it writes very smoothly. My only quibble is that there isn't much ink in the pen! If this is your go-to-pen, you'll find you run through the box fairly quickly. I've had to give a number of mine away because once people see the way they work, they want one!
