Uni-ball UMR-85 Gel Ink Pen Refill - 0.5 mm - Black

This refill is usable in UMN-207 Micro, UMN-152, UMN-105, or UMN-138. I tried it in an UMN-138 pen body from Jet Pens and it writes smoothly. A friend complimented on my writing while I was using it, and I pointed out it is not me but the ink quality that is responsible.

This pen refill is a direct replacement into the 207 Premier from Uniball, if you like the alpha-gels, the 207, Premier only, has the same grip with more cushion than the alpha-gel slim and a firmer grip than the fatter alpha-gel. The 207 Premier is a bit more attractive and comfortable to write with as compared to the fat and slim alpha-gels and accepts gel ink refills rather than ballpoint. I have yet to find a pen I enjoy taking notes with more than the 207 Premier, with these refills replacing those that come standard. My suggestion would be to order a few of these refills and have a 207 Premier waiting for a transplant by the time your order comes in the mail. I promise you will not be dissapointed if you've been searching for a comfortable pen that can lay down a very fine line and still handle a days worth of note-taking without skipping.

Smooth ink flow. Color of ink is identical to the color of grip on the UMN-138 RT blue-black pen. This refill is usable in the UMN-138 pen as well.

Bought this gel ink refill to replace the black color in the MF3 multi pen, great color.

I fit my 207 Premier with this per the earlier comment and it works great!

Took notes all day, no scratching or skipping.
