Beautiful writing experience
We've used these for some time now, both the fine and ultra fine. They last well, perform consistently and allow a lovely flowing writing style. Comfortable to hold and I've never had a leak. Good value when bought in larger boxes.

The only pens, my boys will use for school. They really smooth to write with, but they do smudge. No issues with ink flow, happy with purchase.

I love these pens. While not the cheapest they write very well, feel comfortable, don’t leak and just keep going.

Great value when on sale!
I am an engineering student and I love these pens for writing maths equations and taking notes. Each pen lasts me a little under 2 months!

Long-time fav pen.
These pens are incredible for normal daily use. I use them in my shop both for my own admin, and for customers to sign contracts. They're fluid and never break up. Nice thin but definite line. Perfect for important documents. This pack also came with a free gel pen, which has a little less perfect line than the wet ink pens, but is absolutely perfect for signing the back of credit cards or similar. I also sometimes find the wet ink pens to soak a little too much on cheap paper, where as the gel pen would be perfect for that. Have used for a decade or so, and routinely get comments in the shop about having nice pens.

Beste Schreibstifte
Ich schreibe schon sehr lange damit und für mich haben sie den besten Tintenflow. Leider sind es Wegwerfartikel. Es wäre schön wenn es recycelter Kunststoff wäre.

Good pens
Good pens if you like smooth pens. I personally prefer finer pens, didn’t read the description. Writes well and it lasts long too even with daily use
