Very Good - Highly Recommend.
Personal favourite easily disposable pen. Very quick-drying ink, relatively smudge resistant, and they provide a smooth writing experience, (having used fountain pens which cost hundreds, these honestly come very close). Highly recommend for every use apart from high-school exams, (they do slow down writing quite a lot).

Good for junk journals etc
Intense colour and good flow on lots of different textured surfaces. Recommended to me by a fellow crafter and I'm very happy with them.

Superb Pens!
This is my second box, I absolutely love the Micro air pens. I used to use another pen for years but once I tried these, I was hooked. I only use these now. I write alot of notes, letters and do various illustration work also and these are so fluid, smooth and create beautiful marks with the option of different thickness of lines but not needing to dent the paper which is great for what I need. They also seem to last extremely long also. 100% recommend!

SUPERB PENS
I have bought several packs of these wonderful pens - 12 and 3 sets. I have just finished a set of 12. I did originally think that I would use them sometimes - but I use them all the time. They are great value for money and I am now going to place my order for another 12-set. They are so good to write with and heartily recommended.

Was finally able to find a pen that was water resistant. They write very smooth, and are perfect for journaling.
