Uni Pin Pen - 01 Pigment Ink - 0.28 mm - Black Ink

I love this pen. Great flow, nice tip - for a felt pen fairly durable - and the ink is super black and stays put under a watercolour wash. It also does not rub off onto the page on the other side of the spread, unlike the copic ones I've used. It rubs off a little if you erase aggressively, but 99% of it is still there.

I love this pen! Very fine line, great ink (waterproof!), writes well, attractive. And a fabulous price! I'm going to get the other two sizes so I can use them for different applications. The 0.28 is a little too fine for my medium sized everyday handwriting, so I only use it for things requiring very small print.

I love this pen! The tip is finer than Monika Pietrasinska.

This is a perfect pen for both sketching and writing that equals if not exceeds the quality of the micron pens. I like that pin pen seems to grip the page when you put the pen to paper. A very highly recommended pen.

In addition to being a great pen with a nice tip, the cap fit is very snug. Why do I consider this a feature? The pen ended up in the wash. I don't know how I forgot it, but I did. When I realized what I'd done, I went to the basement expecting to find a bunch of clothing with nasty black stains. Instead of ruining a whole load of laundry, the cap was still snugly attached. The spin of the washer and dryer had pulled extra ink out of the tip, which had pooled in the cap, but the cap had not leaked or flooded and my clothes were not ruined. As a bonus, the pen still worked after I'd cleaned out the cap. I will forever love this line of pens for saving me from my own absentmindedness. Unfortunately, someone at the office ganked it a week later.
