uni-ballUB-188-M Micro Air Rollerball Pens. Premium 0.5mm Nib for Super Smooth Handwriting. Writes Like a Fountain Pen. Fade and Water Resistant Liquid Uni Super Ink. Box of 12 Blue Ballpoint Pens

Started running out of ink after 2 weeks. I had barely written 20 sides of A4, a pen should clearly last longer than this. There are also marketed as being 0.5mm nibs, but they are no finer than my 0.7mm pens, and that is still quite a thick line. They are also marketed as being "pressure senstive", like a fountain pen - this is a gimmick. The pressure seems to make zero difference, unless I'm literally about to push the nib through the paper, only then do I get a thicker line. But this would apply to any pen, and I hoped it would be the other way around - that little pressure would yield a thinner line. No, its either normal thick or very thick - no fine lines to be had from these pens.

Needed to restock because I love these so much! They came in good condition and work great

Have bought these for my job for a couple of years now. You can't beat them. Comfortable to write with, no smearing.

Disappointed by this product. Marketed as 0.5mm fine non but writes like a 0.7 medium. Don’t expect thin lines, it’s a thic boi

I guess they write. But distinctly underwhelming. They certainly don't "write like a fountain pen" as advertised.Mine are far prone to skipping and smudging than a fountain pen. I've used better rollerballs as well. Wouldn't buy again.

These pens are the best purchase of my life, the easiest pen I’ve ever used. Makes writing wonderful and enjoyable. Would recommend to anyone. But you will have to use good quality paper for this pen for optimum pleasure and ease.

Truly Comfortable pens. Great weight. I journal daily and use these pens. Without them I’m lost. The red tone is a bit gregarious but still great great pens. Reliable and comfortable.

As pens go they are expensive but perfect for my child who snuggles with writing as you don't need to use alot of pressure
