AIR Micro - 0.5mm Fine Rollerball - Pack of 6 Pens - 4 Black, 1 Blue and Red (Assorted Collors), Packing may vary

This product is amazing it is a must buy again it kinda smudges but it writes smoothly and the thickness of the ink and the pen itself is amazing it is a value of money for people who like to write!.

These are my favorite pens! I’ve been using them for several years now. They write so nicely!

Love how smooth they write! Do not bleed through and dry instantly. Probably my new favorite pen!

Good pens. I use them for school and other things. Pretty expensive but still good.

Nice variety but the thickness of the line is more like 0.8 mm which is somewhat bolder than what I had hoped for. The fine line would have allowed for more detail in the presentation; when writing in small spaces, bold lines give blurred results. I am satisfied with these pens.

I love these pens!! Will continue to buy them.

The pen quality is good and it's comfortable to hold.

These pens were recommended by an artist/teacher who does a lot of hand lettering on her art journal pages because she finds that they write well over textured backgrounds, over different kinds of mediums used (watercolor paint, acrylic paint, inks, glues), and are permanent when dry. I've only used this pen to practice lettering on smooth paper so far, and they do write so nice and smooth. I'm looking forward to using them on my next art journal page.

This pen is just amazing!!! Super smooth and quick dried on the sketchbook. Normally, I am using this pen for urban sketching and those pens doing great! I trust all Uni products! Very well made!!! Thanks!

These are my son’s favourite pens- he writes a lot and asks for these one specifically.
